Billet Engine Bullshit
Well, long
story in short form...We built him a 00-1040 2" LSR
2-1 Pro Stock for his new FXR and it, flat ass,
did not fit.
Secondly: The
bike had a 6 speed Baker which is .500" wider than stock
and it's center hydraulic banjo fitting eliminated one
of our the three LSR exhaust bracket bolts. Stay with
the 5 Speed. Three days of work to get a custom exhaust
designed with green tape to prevent scratches.

Welded
Non Removable Baffles
All LSR 2-1 designs have a welded-in,
non-removable, baffle. LSR Pro Stock 2-1 designs have
no baffle (optional welded-in baffle at time of order).
00-1416 Quiet Baffle is optional on our +5"
Slash Cut designs.
There is no possibility of a baffle or end cap
coming loose because there are none. Zero maintenance for
life. No tone change over time,
S&S V111 Cone
The S&S machined cone does not taper immediately from the engine case as does the OEM item. We have had to make changes in our "B" style exhausts to clear this non-stock cone. It's always something.

blow by creeping cages like a tornado. And I must say

S&S T143
with B3 Heads
143 Cubic Inches
for your Dresser. Another way to spend $10,000.00 to
$15,000.00 to climb the Horsepower mountain. We are
making exhausts for these with out integral two bolt B3
flanges. The exhaust port dimensions are not OEM Harley.
There are slight variations between the B1/B2 and B3
S&S heads.
We have made
custom parts for these two bolt T143 B3 cylinder heads.
Available for the four product ranges we
manufacture...Quiet (LSR 2-1 Black Hole) to Full Race
(LSR 2-1 Pro Stock). All use 2" primary tubes.
The new two bolt
LSR 2-1 B3 Flange is integral, free rotating, to the
exhaust port. Full tapered cnc machined venturi for 2"
primary tubes.
Uses a
machined1.875" I.D. Billet Alumiunm Gasket.
S&S SA B1/2/3 Heads
We have been asked by customers to provide
LSR 2-1 exhaust systems for B1 / B2 / B3 heads originally
found on EVO and 145" S&S Tribute engines and later
T143 engines. Early B1/B2 four bolt flanges. Later B3 use
two bolt flanges.We make both. The diagonal dimensions are
the same two to four bolt patterns.
We have LSR 2-1, LSR 2-1 Pro Stock, LSR
2-1Pro Stock Spyder and LSR 2-1 Black Hole designs for
these three S&S cylinder head variations.. Pictured
above are our laser cut flanges and cnc machined hour
glass shaped venturis that we heliarc to the B1 / B2 / B3
LSR 2-1 exhaust systems.
We have a specific fixture for the 126 S&S and T143 SAB2 / SAb3 Twin Cam Dresser systems as the billet cam cover is not OEM.

Twin 5/8" Shaft Spherical Bearing
In the picture
above, at the top, are some really questionable Delrin
spacers that are sold with tubular inserts that, with
the help of some grease/paste, are supposted to act as
bearings and pivot in the Delrin. This is by no means
a bearing in any sense of the word. It is patently
stupid...crude with stiction. Those go in the trash.
At RB Racing
we machine up some spacers, black items pictured
above, that allow you to use the OEM 9208 Spherical
Bearing...that is actually a real bearing...and allows
you to retain your one or two-piece 5/8" axle. We
install these in the pre 2009 Twin Cam swingarms we
modify for 2" adjustment, high horsepower, FXRs.
If you choose to do this be aware you must change your rear wheel, axle, and brake assembly for the 25mm rear axle and later model brake calipers. Do not attempt to drill or ream your transmission case for the late 3/4" axle. There may be more Delkron FXR cases with 3/4"pivots being made (?)...even though Delkron went away long ago.
We can supply the complete swingarm ready to fit your FXR or earlier EVO Dressers. FXR and Dresser swingarms have different shock locations.
Real World
Tuning Package
When you order a complete LSR 2-1
exhaust with the RSR Air Fuel
Ratio Gauge there
is a $75.00 discount on the total price. You can observe
while you ride in the real world to evaluate transitionals
and wide open throttle . In actual dyno tuning you really
have to hold one "site" i.e. the intersect of load and rpm
to get an accurate feedback. That's why you see Superflow
engine dynos doing step testing.
Single gauge is for carburetors.
Dual Gauge is for sequential EFI (Example TC Delphi in FXR)
The problem is things heat up in these air cooled engines . You can really only do one wide-open throttle pull and one rpm site before the engine heats up too much. Best do real world tuning while you ride and then evaluate, in real time, your jetting with the RSR milli-second fast RSR Fuel Ratio Gauge. Real time monitoring when you ride is the only way you can evaluate transitionals, acceleration pump, and wide open throttle...all in the real world air and on the road like you do normally.

One and One in Reserve
Customer writes:
"Hello, The exhaust and AFR gauge arrived a few weeks ago
and b/c of time restrictions I was finally able to get
them installed, yesterday. I just now returned from
my first ride - a quick 30 miles - with your new
components. Here are my first impressions;
Fit - Close to perfect - a little tight upon installation
and had to wrestle slightly with it - attributed to my
lack of experience. However, much better fit by far
compared to the previously installed Supertrapp Supermeg
series pipe (not the original stock fitting smaller
Megaphone series), which required a homemade mounting
bracket.
Appearance - By far, the FXR looks more badass with the RB
LSR 2 into 1on it compared to the Supertrapp Supermeg.
Sound - Louder and throatier than the Supertrapp
Supermeg. I always wear a set of high tech
custom-made earplugs, and the pipe sounds great when
wearing the plugs. I particularly like the reversion sound
(or water it’s called) when climbing to and shifting at 4K
rpm.
Tune - The AFR shows that I am running slightly more than
rich, as next-to-last red LED is consistently lit during
highway cruising range (65mph-85mph). Should I swap down
to the next leaner intermediate jet on the Super E?
I’m pretty sure that a .031 jet is in there, now.
Overall, I am highly satisfied and pleased with the pipe
and your customer service. I know I made the correct
choice and believe that the RB LSR is the best 2 into 1
pipe choice for any FXR for looks and performance. Thanks
for all of the patience and professionalism you
demonstrated in answering my email questions through the
past couple of years, during which I changed my motor,
transmission and foot-peg set-up, thus delaying my
purchase by ultimately effecting the decision on style and
shape of the custom-made pipe. I now feel that the
FXR-build is finally complete - famous last words!
As promised
attached are several photos of the newly installed RB 2 in
1 pipe on my FXR. Believe it or not, this bike
started out as a 1999 FXR3 (green flame). I bought
it pre-owned in its stock form in 2009 with only 1,600
miles on the clock. Now, the only stock components
that remain are the seat (which I actually had modified
into a 2-piece hinge & latch set-up), clutch &
brake levers, brake pedal and some fuses and wiring.
I felt so guilty that I recently bought a close-to-stock
’99 FXR3, last year. Going to keep that one
completely stock. Apologies for the busy / distracting
background noise in the photos. Hope it doesn’t
distract too much from that badass looking pipe. Thanks
again!
Regards. Ned".

Dumb and Dumber:
Changing 3-Point OEM FXR to Dual Mount 47584-09
BBC engine
mount... These eliminate the front heim-joint adjustable
single point Lord mount to a double fixed-mount system
that Harley uses on their late model Dressers. The
original three point system pioneered on the FXR, inspired
by the Norton Isolastic system, took more time to align
but worked well on Baggers and the FXRs.
A couple of
aftermarket concerns are marketing this to FXR owners.
Beware.
This fixed system
was Harley's production-driven solution to go to a simpler
two point system and skip the alignment issues on the
assembly line on the upper and front adjustable Heim joint
3-Point system. With fixed rubber stops there is no
possibility of alignment as there was with the OEM three
point system.
There
is a procedure for stock alignment which is not
possible with the BBC mount.
Keep in mind that
the original FXR was maybe 58 Hp. These days people are
stuffing 130 Hp S&S 124" motors in them that, with B2
Heads, can get up to 150+ Hp. Weak
swingarms, worn bushings, dead engine mounts,
steering bearings that were never checked, no steering
damper etc...You have a responsibility to make your FXR
handle safely. With
turbos we
are aware of this.
Put these in the
trash.

New FXRP/D
Exhausts...(Floorboards)
We borrowed this
1984 FXRT because it was pretty much dead stock. We used
it to design new LSR 2-1 "C" Style exhausts. These will be
available in the five product ranges we currently offer.
FXRT's are sort of rare these days as they weren't around
a long time and people tended to buy Dressers instead of
this "Sports Tourer". The FXRTs have non-standard
floorboards and the earlier style 5 speed transmission
with the clutch cable coming around the left side. We had
to design all new mounts and fixtures. The stock rear
rubber Lord mount is not used as we provide a three point
transmission mount. Harley abandoned the Lord mount later
on as they all broke.
This is the
finished part. It's hard to find a clean FXRT these days.
This one is super clean.
00-1385 LSR 2-1 Slash Cut, C Style, 1 3/4" is the most common part.

Customer writes: "I must say your pipes are extremely well built. They fit perfectly on my FXRP. Most pipe Manufacturers do not even have my bike listed. Just got the bike on the road today. Compared to my old Super traps which are tinny in comparison. As for sound, they have a deep throaty note to them. Going on a 2000 mile trip in a month and will have a better feeling about the performance difference. The only thing that I noticed first off was the RPM increased by about 200 at idle over the old pipes. Chuck"

S&S 113, Fat 5 Transmission, FXR
Prototyping never
ends. In this case a customer had a 113" S&S engine with
a custom machined Jim's Fat 5 transmission. We told him our
standard 00-1013 B Style Slash Cut FXR pipe would never fit
and he would have to bring the bike by to have one made "on
the bike".
We tucked the from
pipes in as far as the clutch cable and frame would allow,
leaving room for the brake pedal.
Shit never ends. If
you have a big inch FXR we have the exhaust system for it.
Transmission mount. We had to use a late model Dyna
transmission mount as the Jim's Fat 5 is not exactly "FXR
std" and it's a lot wider...Plus this customer had some sort
of rear wheel/transmission stabilizer that made things even
more complicated.
After the pipe is
tacked together then a custom fixture is made. This 2"
exhaust gets a Black Ceramic finish with black heat shields.
It replaces a Supertrapp 1 3/4" that had a zillion discs
that was wrapped up in header wrap. Bike will be driven from
LA to New York. Shit never ends. If you have a big inch FXR
we have the exhaust system for it.
We ship LSR 2-1
exhausts direct to customers in Australia. Middlemen
always seem to want to sell things but not actually buy
things...and when they do, the price goes sky high and
often they order the wrong parts for the customer who has
to wait forever... Too many layers.
FXR Test Vehicle
We like FXRs and we instrumented ours with our digital Tachometer, GPS Speedometer, Dual O2 Gauge and Gear Indicator. No it's not a FLHX. It started out as a 1999 FXR CVO2 that we put on a 5 gallon FL tank and got rid of the solid rear wheel and the 21" front wheel. We also converted it to chain drive and put on a Hayabusa steering damper and one of our LSR 2-1 1 3/4" B Style turn out exhausts. We also fuel injected it with one of our closed-loop RSR Injection Systems.
We had Jim's Cycle Painting
put on a simple one color scheme as the cops seemed to
be attracted to our blue tank, yellow rear fender and
purple front fender. Clown bike. Painters are weird.
We just left the color up to Jim. He painted Seven
time F1 Champion Michael Schumacher's Bobber Harley so
he was a pretty decent painter. Jim passed away due to
a heart attack. Another painter gone.

FXR..Evil Twin
Mike Geokan widened an FXR frame by 1 1/2" , added some Buell parts, put in a high compression 100" motor and had us make a C Style LSR 2-1 with a whopping 1 1/2" of offset to account for engine and transmission offset. Since Mike is an excellent fabricator he made his own transmission to exhaust mount out of aluminum plate. Mike is usually working on his Bonneville Bullett, but since it was completed he needed a new project. 00-1017 LSR 2-1, C Style, Slash Cut, in chrome with heat shields.
Customer writes: "Thank you very much. Your pipes look, sound and feel awesome. It was worth the wait." Many custom touches on this one. Lots of work. Pretty much everything has been changed. Most people agree the FXR frame was the best Harley ever made.

FXRT
Customer writes: "Here's a picture of the RT. The exhaust performs perfectly, and it sounds great! Installation was no problem and the packaging was beyond compare. The only issue I had was the foot brake hit the shield. Not the pipe before I put the shields on. I adjusted the pedal up, (it's a bit high but works). Other than that, I get a lot of compliments on it. Also, it never pulled a wheelie going into 2nd gear before! Thanks again,-Nick".
00-1011 1 3/4" LSR 2-1 B Style Chrome Slash Cut with hear shields. Pedal clearance with heat shields is tight and requires some adjustments or spacing. FXR's came along 20+ years ago and disappeared then reappeared in CVO special order, short run status. Probably the best handling bike Harley made.
"B" Stories
Here's a couple of photos of my bikes: the flame 1993 Softail has a 120" Ultima motor, RB LSR 2" pipes, and dynos at the rear 126 hp and 130 ft. lbs. of torque. The little guy is a 1991 FXR Low Rider with an 89" stroker motor, 1 3/4" RB LSR, and dynos at 94 hp and 101 ft. lbs. of torque. I've had these pipes for over six years. Both pipes rock ! They make the best power, and have a deep menacing growl ! Don't forget my new Cloisonne RB LSR tag for the little guy......Thanks......Carlos." We sent him a new style tag.
Military Discount
We offer a 10% discount to active or prior service both US Military and the Coast Guard on LSR 2-1 exhaust purchases.
System Approach to Tuning
1. LSR 2-1
Exhaust... Proven performance gains.
2. RSR Air Fuel
Ratio Gauge...Observe in the real world. Dynos are great
but we don't ride them.
Soot
Whenever you look at an exhaust and see it caked in black soot you know the bike is not running or tuned correctly. Back in the mid 1980's we did a carburetor development program for Keihin Corporation for their 41mm CR Race carbs on both Shovelheads and the new Evolution motors. When we were finished the bikes got 56 mpg cruising and 46 mpg if you ran them harder...and after 500 mile tests the pipes were perfectly clean inside and the exhaust ports were dead clean.
If you take
the exhaust system off a modern Closed Loop BMW, as we
have, you will find them dead clean or whitish inside.
Harleys should be the same.
We always ask
what mileage people get from their "tuned" or modified
Harleys after "Dyno tuning"....The universal answer is
37 mpg or less. If they don't know, we ask them if
they have to gas at 100 miles. Most do.
Once a customer bought an exhaust from us and took his bike to two different dynos in search of the "117 Hp" he was looking for for his 103...He got 110Hp. After pissing and moaning we told the guy to give us our exhaust back and we found it caked in soot. So much for tuners and their tail pipe sniffers that see lean reversions...They just kept adding fuel. You tell the customer to put on our RSR Air Fuel Gauge to monitor the mixtures F/R in the real world...No, they want a "Dyno Tune". We have dynos...we know what they do and can't do.
Pictured above is the exhaust port from a 2017 Dyna Low Rider S with about 100 miles on it. No soot. Delphi engineers seem to have done a very good job. Looks like the port you would see on a BMW. Now, when your "Tuner" gets finished with it, it will most likely be full of soot. Logic plays no part in people and their toys. EFI is complex...put in different cams, change air cleaners, port the heads and all this goes out the window. Brave new world.
No soot.
RSR Air Fuel Ratio Gauges...Real World Tuning
The Mother of all gauges! Not a gauge, but a precision tool that will tell you exactly what your engine is doing in real-time. Gives you instantaneous read-outs of air/fuel ratios from 17:1 to 10.5:1 and indicates maximum power ratios. Four color display is easily read in direct sunlight and automatically dims at night. Waterproof, billet aluminum construction. Your significant other will cheat on you but this gauge will never lie! It won't keep you warm at night, but a perfectly running engine will look and sound the same when you wake up next to it the morning after.
Single RSR O2 Gauge: Reads the front cylinder in non-efi models. It is simply the best way to evaluate the tune of your motorcycle and saves expensive and often inaccurate dyno time. Real world tuning while you ride...Observe and then make adjustments. Mounted permanently. Waterproof.
Mounts....Roll Your Own or Buy One
The gauges have a center back mount 5/16" x 18 x 1/2" Stainless Socket Head Cap Screw and stainless lock washer. You can fab your own bracket for this or use the 06-1025 hard anodized Billet Mount System for either 1.00" or 1.25" handlebars $49.95. Optional is the 06-1024 two piece laser cut 304 Stainless Steel mounting tabs for either near handlebar clamp or up the handlebar mounting: $9.95.
Since we have
been doing closed
loop fuel injection systems for Harleys
for more than 30 years and have been putting O-Sensor
Ports in our exhausts for the same amount of time, we
have both single and dual O2 ports for our full range of
exhausts. Our RSR Air
Fuel Ratio Gauge is the best
investment you can make for monitoring and optimizing
your engine tune.
All LSR 2-1
exhausts come standard with one or two O2 ports
(Sequential EFI models)...18mm or 12.5mm. O2 or Lambda
sensors are a necessity for either carbureted or non
closed loop efi (Weber Marelli and Early Delphi)
Harleys. We should know, as we have a lot of experience
with them and have been doing Closed Loop EFI systems
since 1989.
The Single and Dual gauges ship with six feet of MIL-W-22759/32 wire. The first 24" is Raychem DR-25 sealed on both ends. If you wish to have a connector at the 24" point there is a $50.00 charge to install either six position (single gauge) or eight position male/female Deutsch DTM connectors with Raychem DR-25 sleeving.
The gauge is housed in a hard anodized round enclosure in a standard 2" format with a 2.250" bezel, center back mount, with a 5/16" x 18 stainless socket head cap screw. The gauge will show fuel ratios from 17:1 to 12.0:1 (or richer). The gauge is visible in daylight and automatically dims for nighttime operation. Only a single L.E.D. illuminates.
Very easy to interpret at a
glance. Scale is, left to right, lean to rich: three
greens, three yellows, two orange and two red l.e.d.s.
You simply cannot "read" spooling digital numbers.
The white arrow indicates the maximum power mixture, the second orange light, which is 13.2:1. Transitory enrichments should not, if the engine is warm (>200F Oil temp), go past the first red light. Readings at the far right side of the scale, the second red light, are simply too rich. Proper closed loop operation will cycle back and forth from green to orange around the center of the display.
It is simply the best way to evaluate the tune of your motorcycle and saves valuable dyno time. Mounted permanently. Waterproof.
Whether your
bike is carb or efi this is the best way to tune...By
riding and observing, not on a static dyno. Dynos are
not exactly real world in terms of loads, airflow, or
transitionals, and even if you had a million dollar AC
Transient dyno room, you would still have to do real
world testing. The gauges are dead accurate and are
millisecond fast responding which makes it very simple
to interpret or remember, even at a glance, while you
are dodging cars watching for cops. We have a Superflow
CycleDyn which
gives a better real world correlation than other
dynamometers but we still evaluate air fuel ratios when
riding.
Anyone who tells
you optimizing tuning is easy is full of shit. Engineers
at Ford say they spend two years just perfecting tip-in
or initial throttle openings. Ride, observe,..then
change or edit. Real world.
Pretty soon Harleys will all be watercooled then you really won't be able to tell the difference between Milwaukee and Hammatsu. "The Man" will be sniffing your butt and planting microchips and gps modules up your ass so they can mail you a speeding ticket and keep track of your movements. They already have data recorders on your car so they know what you were doing when the biggie happened. Brave new world. Monitor your engine to get the most out of it before the NSA monitors your tail pipe.
RSR AFR Gauge Customer Comments
Customer writes: "When the gauge arrived I knew it would be of a very high quality, it has far surpassed my expectations. I was very eager to get this installed and take a look at my tune. Amazing to see how little adjustments on the carb effect the AFR. As a result of this gauge, I have dropped one size on the low speed jet, raised the clip on notch and confirmed the main jet on my Mik48. Thank you, I really like this gauge. Ed"
Wideband O2 Adaptations
Systems that typically use Bosch LSU 4.2/4.9 wideband sensors for self-tuning have a built-in problem. First, the "map" has to be correct before any of this self-tuning takes place. Secondly, the real issue is the sensor response time, i.e. the time it takes the sensor to stabilize, and for the ecu to make a corrected output. No matter what they tell your there is a significant delay between the reading and the correction, during which time the engine will be at another rpm/load site . This can be on the order of 980 Ms for the Bosch sensors which is why, in dyno testing, they use step tests for a number of seconds, letting the engine stabilize at specific load/rpm points, before any measurements or changes can be done. Constantly rewriting RAM locations with "corrections" on the fly is never going to be correct.
The OEM narrowband Delphi
system actually works twice as fast at 500 Ms and the
map, as delivered by Harley, is correct. The Delphi ecm
has the ability to adjust about 20% in small increments
(block learn multipliers) to factor for air cleaners
slowly getting dirty etc. It already is self-tuning
except at wide open throttle.
Do Not Use OEM Gaskets
LSR 2-1 Exhaust Systems must use our CNC Machined Billet Gaskets (part number 00-1000) and our close tolerance aircraft exhaust nuts (part number 00-1001). The above OEM woven gasket will not work with our machined Turbo Venturis. Four special aircraft exhaust nuts come with the system but you must order four extra ones for $3.00 as they are easily dropped and the OEM 5/16" x 24 hex nuts will not "turn" on our machined Turbo Venturis.
We also offer machined from billet exhaust flanges. If you have a 2004 or later bike it will probably have the thicker exhaust flanges which are not compatible with our Turbo Venturis. Early style OEM Evo chrome die cast flanges and clips or our billet parts are called for. Our Chromed Billet Steel Flanges and clips are $29.95 per set and are stronger than any oem part.
We have had several instances where people encounter "difficulties". Invariably, it is traced to someone not using our billet gaskets. The billet gaskets insure proper fit of the LSR 2-1 system and are designed to work with our Turbo Venturis to increase exhaust flow.

Big Motor FXR
All the way from Great Britain, a 131 Merch in an FXR custom. With forward controls we do a different "C" Style FXR and slip the rear pipe to prevent fracturing just like we do on other rubber mounted engines. Pipe is mounted off of the transmission. As you can see there is nothing stock on the bike. It takes a lot of effort and parts chasing to do this, especially with long supply lines. A long time ago the "Ton" was a magic number. This one will do this in a heartbeat. Dinosaurs have evolved. LSR 2-1 with 2" primaries.

LSR 2-1's Bonneville,Dyno &Track Proven
If you want to make power on a multi-cylinder engine you have to use a collector system. Whether it's a V-Twin or a V-8 it's the same, and no less an authority than the famed engine builder Smokey Yunick will tell you that. Not using free exhaust energy to help your engine breathe is downright criminal. No matter what the conventional wisdom is, staggered duals on a Harley will not make more power. You simply cannot escape the fact that a properly designed 2-1 will give you more usable torque where you need it, in the 2000 to 4000 rpm range, which means less downshifts and less rpm to get the job done.
A set of short staggered duals at peak rpm can be made to produce good power but they will be dead on their ass until they get there, whereas an engine developed around an LSR 2-1 exhaust can be made to perform from the bottom up with no dips in the torque band! If you don't believe this then why is it always that the top Pro Stock bikes, cars etc. end up running collectors systems? Damn right they work! If you don't think torque between shifts or when you roll the throttle on, then buy those long sewer pipes or some short curly drag pipes you saw on the Discovery Channel.
Check out our new Exhaust Technology Section for information on how all this works.
New Cloisonne Tags
Like in the adage "The relentless search for perfection" we have upgraded the logos we put on our LSR Exhaust Systems. Previous tags were stamped and formed aluminum with silk screened details. The new cloisonne tags are a precision die struck brass, nickel plated, with powdered glass fired in an oven then polished to a jewelry finish. These are direct replacements for our older tags and are available for US $25.00 postpaid via US Global Express (foreign) or Priority Mail (domestic US). They come with black headed rivets and are riveted in place with a light coat of high temperature silicone (Permatex 598B) behind the tag.
These are direct replacements for our older tags and are available for US $20.00 via US Global Express (foreign) or Priority Mail (domestic US). They come with black headed rivets and are riveted in place with a light coat of high temperature silicone (Permatex 598B) behind the tag.
Our testing has shown that the
Harley V-Twin is extremely sensitive to back
pressure which is why 2-1's that use small or
restrictive collectors don't breathe well, and
why restrictive
baffles shut
the motor down. Disc type baffles are good for
spark arrestors on dirt bikes but they have no
place on a big inch V-Twin. You don't make
power by adding restrictions to your exhaust
system whether it's a bunch of stainless discs
or some damn piece of aluminum billet machined
into a Harley butt plug!
Ever wonder why they had to put
a hole up the center of the discs? Well, one
reason was the discs are so damn restrictive
you have to have several pounds of them to get
enough flow through their waffle shaped
passages. Good mufflers, but they have nothing
to do with performance and they sure as hell
do not create vacuum as has been claimed.
When you get confused by all the bullshit simply ask the following question.." Do they run them in NASCAR or in Formula One?". Nope, they run straight pipe collector systems without any stupid discs or aluminum butt plugs.It's always funny how when the money is on the line, all the little things like discs, billet caps, anti-reversion flaps, reverse megaphones and other such nonsense somehow don't make the field.
All RB Racing LSR Exhaust Systems feature our "new" (we've been quietly doing it since 1985!) CNC machined Turbo Venturis that actually "scavenge" to help your motor breathe. Machined from billet, these allow full 2" flow and eliminate the phony restrictions that other 1 3/4" to 2 1/4" pipes have at your exhaust port. We supply special close tolerance aircraft nuts for your exhaust studs because our machined venturis are too wide for a standard hex nut.
Our CNC machined Turbo Venturis are not compatible with the "bowl-shaped" late model OEM exhaust port gaskets or early style "flat" gaskets for the LSR Exhaust Systems to both fit and seal properly. The narrow machined flat face of the Turbo Venturi must seat against a flat surface, not the bowl-shaped late model gaskets. Using the LSR Exhausts in combination with the wrong gasket will cause misalignment, inability to tighten the provided close tolerance aircraft nuts, and will force the bowl-shaped gasket into the exhaust port.
Mandatory for a nominal charge of
$9.95 are
a pair of our LSR CNC machined gaskets which mate
perfectly with our Turbo Venturis. These are
proven in over 16 years of use on our race and
turbo applications...the only gaskets that will
stay in a turbo bike for 25,000 miles! These
gaskets prevent any gasket "creep" into the
exhaust flow and are one more thing that will give
you "an edge" on the competition. We always
wondered why people would port their heads, put in
bigger valves and then squish the gaskets into
their exhaust ports.
We bet you never paid attention to what was going inside your exhaust ports for one very simple reason...you can't see what's going on in there once the pipe is tightened! The LSR CNC machined gaskets also insure perfect alignment of the exhaust system. Most fitment and alignment problems are traced to using either the wrong type of gasket or using old gaskets that have taken a "set". We've always used these on our race applications and it's time everyone who's concerned about performance should do the same.
All LSR 2 into 1 exhausts require special close tolerance aircraft nuts to bolt the LSR Turbo Venturis to the exhaust port. Standard 5/16" x 24 hex nuts will not fit. Each exhaust comes with the required four nuts. It is recommended that you order an extra set (4) of these nuts, part number 00-1001, when you order your exhaust.
STD Cylinder Heads
We make special flanges for STD heads that match the rectangular bolt pattern that STD machines. If you order a RB Racing LSR 2-1 Exhaust you can order these flanges which have been designed to fit our standard turbo venturis. RB Racing Part Number 00-1003. Sold per pair $29.95. When you order a RB Racing LSR 2-1 Exhaust system we either polish and chrome these or bead blast and ceramic coat them.
Goo
RB Racing LSR 2-1 exhaust systems
use either one or two slip joints depending on
the model. We suggest you put a coating of
Permatex 598B ULTRA BLACK in the slip joint.
None of our slip joints use any clamps because
then they wouldn't be slip joints anymore. In
the case of ceramic coated LSR exhausts
the coating is thicker than the chrome and the
ceramic finishes have a higher coefficient of
friction making the slip fit somewhat more
difficult. The use of ULTRA Black will allow
easier assembly of the exhaust into the slip
joint.
In actual operation the inner pipe gets hotter that the outer pipe and they grow into each other and form a tight seal. The 598B is a non hardening gasket material and will prevent any leakage from condensation that forms in the pipe and, with the usual carbon particles, will actually seal better over time. It also makes the pipes easy to take apart later on. Get a tube before you install your RB Racing exhaust system.
All RB Racing LSR exhaust systems come standard with a machined and heliarced oxygen sensor boss just below your front exhaust port. This port is designed to accept and oxygen sensor (18mm x 1.5mm) which will allow you to use our RSR Air/Fuel Ratio Meter to tune and monitor in real-time your air/fuel ratio. Also, if you really wish to get 55mpg and kick ass, our RSR Fuel Injection's closed-loop heated O-Sensor will plug directly into this port. 06-1025 billet handlebar bracket.
In the
case of OEM fuel injected models, either Delphi or
the earlier Weber Marelli, two O2 ports are
installed either 18mm or 12mm.

Customer Writes: "Hi, Its been a long time since we have talked. Wayne Keyworth turned me on to your exhaust system. Since then I have enjoyed the performance ever since the installation to the bike and have ridden the bike with pride and out front of the pack with performance of the exhaust and slight cam and carb modification. Real runner it was! Lifetime of remembrance of out-performing the others. Nothing like riding in a pack and cracking the throttle and letting loose leaving others behind no matter how fast or tough they look . Knowing you just have a 80 cu. with mild cam/carb. loaded with all the road pack and passenger.
The reason I'm writing you is, I just purchased my my first BAGGER, I was searching for a performance modification . Pulled up your web site from my previous encounter and seen my old bike made me feel PROUD to have been able to make the web site of such a performing exhaust system manufacturer with just a mild stock bike , That I would challenge any bike/vehicle on the road with confidence and enjoy telling them about it at the next stop for fuel.
My new ride is a 2006 FLTRI Road Glide I don't know what California smog regs are going to be, however, I will be looking for some changes to get me back to the crisp throttle response of my old bike even thought . I have discovered music while you ride. I'm looking for the performance I achieved of the 2-1 system, flow to the rear of bags . Appearance/ performance always wanting something different.
Thanks again, really enjoyed seeing my old bike. Made me feel proud!"
FXR: There are FXRs and then there are aftermarket FXRs like Kenny Boyce frames and a variety of "Rubber Mounted" pro street and quasi-Softail designs. For all of these we provide a 1/4" steel plate that bolts to your transmission. The bracket is slotted to allow for variations in engine mounting and has a selection of dowels that take into account the different transmissions available. The bracket attaches directly to the back of the LSR 2-1 pipe, which has a slotted bracket heliarced to the pipe. The bracket does not interfere with billet aluminum swingarm pivot mounts like those on Kenny Boyce frames or other aftermarket pivot mounts. Pictured above is an LSR 2-1, 1 3/4", C Style, Turn Out on a 1990 FXRS that has made three trips to Sturgis from California.
DYNA (Evo): Transmission mounted. 1/4" laser cut steel plate dowel mounted. No oem mounts are used. Remove oem mounts.
DYNA (TC88): Transmission mounted. 1/4" laser cut steel plate dowel mounted. No oem mounts are used. Remove oem mounts.
Mounting Torques
For flanges and mounts we recommend 15 foot pounds of torque. On exhaust flanges you do not use any locking compound as our nuts are self-clinching. On bolts for frame and engine-mounted brackets we recommend that the threads be clean and that a low grade (Blue) thread locking compound be used with 15 foot pounds of torque. Bolts and nuts on our slotted brackets do not require a locking compound but can also be tightened to 15 foot pounds.
In lieu of torque wrenches do not over tighten exhaust flanges to the point where they bend. In the case of bolts going into transmissions and into frames also do not attempt to see how strong you are as aluminum threads and bolts are weaker than you and your wrench are. Simply tighten things till the bolt stops and give another partial turn to firmly snug it. The last bit of tightening actually stretches things a bit and the tension holds things tight. Tightening should always be done in a sequence. Never finally tighten one part then go to the next...Always loosely tighten things in sequence and then finally tighten things in sequence.
The exhaust should never be installed with any of its elements in tension. It has to rest in place without strain and be tightened without strain.
We employ split lock washers on most fasteners to prevent counter-rotation. This works surprisingly well if the bolt is properly torqued or tightened.
In any case, you have a responsibility to tighten things or at least check periodically as part of your normal maintenance. Harleys do shake and try to kill anything attached to, or even near them. If things get loose the additional shaking moment can break bolts and destroy threads.
General LSR 2-1 Installation Sequence
1. Remove the OEM exhaust and exhaust bracketry. If the bike has floorboards remove the right floorboard.
2. Pry the OEM exhaust gaskets out of the exhaust ports. We use billet gaskets instead.
3. Install the frame or transmission bracket provided. Use Blue Loctite on the mounting bolt threads into the transmission. Lockwashers under the bolt heads on the transmission mount. If through-bolt like on early rigid Sportsters or Shovels use lockwashers under the hex nuts.
4.
Front and Rear primary tubes: Install
billet flanges and clips. Install front
pipe loosely with billet gasket and nuts
provided. Loosely affix the front heat
shield to the pipe as you might not be
able to install the shield later with
the rear pipe in place. We use 1/4 drive
ratchet plus extensions and 3/8" socket
and a 3/8" wobble for the exhaust stud
nuts.
5.
If the rear pipe has a slip joint
(rubber mounted C Style) slip the rear
pipe into the tail section. You may use
Permatex ULTRA BLACK.
6. Begin slip of tail section/rear pipe into the front exhaust slip joint (You may use Permatex ULTRA BLACK) and work the rear exhaust and billet gasket into the exhaust port. Loosely affix exhaust stud nuts provided. We use 1/4 drive ratchet plus extensions and 3/8" socket.
7. Slide 5/16" x 18 bolt(s) into slotted bracket on back of exhaust and thread these through the mounting braket. Loosely affix with lock washer(s) and hex nuts provided. Some exhausts may require a spacer (provided) between the exhast slotted bracket and frame/transmission bracket.
8. Gently tighted up all fasteners and nuts. Nothing can be in tension. You may use a rubber mallet to seat the slip joint(s).
9.
Install remaining heat shields and
tighten front heat shield (5/16" Nut
driver). Completely wipe the pipe and
shields down with a clean cloth to
prevent grease and oil stains from being
baked on.
10.
Run bike briefly in place. Let it cool
down and retighten fasteners. Reinstall
the right floorboard with hardware
provided.
11. If ceramic finishes it is wise to go through several heat cycles. On modern efi closed loop systems they go into closed loop within minutes. Let bike idle for a few minutes then shut it down to let it cool. Several sessions of this will cure the resins as they are only oven-fired to 400F. Exhaust temperatures are >1000F.
12.
Double check all fasteners and ride the
bike. Check your work afterwards. You
bought a Harley so you are already
showing signs of dementia.

Customer writes: "First, I have had your LSR 2-1 C w/Turnout on my 98 FLSTS for about 4 years and 32,000 miles. It looks great, sounds great, and of course, performs great.
Second, the mechanic that works on my bike also drag races a Shovelhead powered FL. He only ran Thunderheader until he rode my bike and did some research. Steve had you guys make him a 2-1 and set new records in his class.
Third, my brother-n-law has a '05 EFI Road King. He was just dying to put some Rinehart true duals on it. I talked him into waiting until he looked at and listened to a lot of RKs before buying. During the year he did this I kept asking what he wanted out of the new exhaust. Finally, he admitted sound and performance. He kept saying I love the sound of your bike and it is fast as hell. So, I suggested the LSR 2-1 C Slash Cut longer pipe. We installed your exhaust, a PCIII usb, and a K&N filter with stock a/c cover and changed the backing plate. His road king has torque and runs like a scalded dog. We both can out run 95" kits installed at the HD dealers.
I provided the background to say this. My B'law took his RK to the HD dealer for the 15k maintenance service. The mechanics went nuts over the exhaust and what it does for the performance. They asked all kinds of questions. They had never heard of your firm or the exhausts. Now comes the kicker and it makes me a little sad (because I have enjoyed having an exhaust that out performs the crap the HD dealers sell). The mechanics conclusion. They are going to take off that HD exhaust crap (their words) and get RB Racing exhausts. Now the word will spread around Memphis and RB Racing exhausts will be everywhere.
It was good while it lasted - having the performance edge over others.
Your exhaust system has been great on my bike for 4 years and 32k miles. Thanks for a great product. I can't imagine having any other brand of exhaust!
PS. Sure wish you would make a LSR 2-1 for Victory Jackpot or 8 ball. The only reason I haven't purchased one in the last two years is because you said you would NOT make a Victory exhaust.
Later…Cliff"
If you are going to use a chassis dyno it has to be a tool and not a toy. At RB Racing we use the Superflow CycleDyn as it best emulates the real world. We use it for development and not for publishing "dyno charts". Most of our work is with Pectel SQ6M controllers which have extensive internal datalogging and playback capabilities up to 2000Hz sampling rates. With the Superflow we can program specific tests and transient sweeps with our turbocharger systems up 750 hp in inertial mode or 500 hp in Eddy Current controlled accelerations.
For
those of you who like Dynojet "Dyno
Graphs"..read
this article.
Steve Cole (TTS MasterTune) who has spent untold thousands of hours on every dyno imaginable has this to say about CycleDyns:
Steve
Cole: "In the development side what I
can say is the SuperFlow when setup
properly emulates the real world much
better. As an example the only way to
get a DynoJet to give you HP and TQ is a
WOT unloaded run. The SuperFlow allows
that plus just about any other
combination you like with real torque
output. So what does any of it buy you
becomes the question. I can tell you
that if we tune to a DJ and get the best
we can, then repeat on the SuperFlow
using real world acceleration rates for
the engine being tested the results are
very different. Take the final
calibrations and run them in both dyno's
unloaded and the DJ developed type
calibration will show the most HP and TQ
in those conditions, on both the
SuperFlow in DJ mode and the DJ. Then
take the SuperFlow controlled condition
calibration and load it in the bike the
power will go up when tested in the
SuperFlow mode again which can only be
done on the SuperFlow.
Now the hooker, take the bike and put
one of the finished calibrations in it
and give it to the customer and say go
ride it and come back after you've
ridden it well, to know how it
feels/runs. They come back after an hour
or so then load the other calibration
and ask them to do the same riding over
and come back again. Each and every time
we have done this every customer has
picked the calibration that was done on
the SuperFlow under the controlled
acceleration modes! So pick what works
for you but there is a difference. Does
it take longer, does it end with a
measurable difference............. YEP!"
When
we have turbo bikes like our Road Glide Turbo it
gets a bit interesting to go testing in
LA traffic with police, cell phone
cameras, and freeway cameras. We still
do real world riding with data
acquisition as the real world is where
you ride.
People want "Dyno Sheets"...see below. We aren't going to test every damn camshaft, compression ratio, piston configuration, cylinder head etc as there is not enough money nor time to do so. However, we do testing for our own race development, R&D, and our personal development platforms.
Dyno Sheets
People call us all the
time asking for "Dyno Sheets"
and we patiently tell them we do
not provide self-serving graphs
predicting fantastic horsepower
and torque gains. Plenty of
customers send us dyno sheets
but, as we've been at this a
long time, we know the tuning
game is too complicated to
provide numbers just to sell an
exhaust. Tuning is a
multi-variable process.
When the EVO motors
came out Jerry Branch published
his famous manifesto on tuning
80" EVO motors...In short,
unless you bumped the
compression the horsepower was
not forthcoming. Same these
days. In 2014 John O'Keefe of Branch O'Keefe ran
an extensive series of tests on
OEM Twin Cam cylinder heads to
see if he could offer a "less
expensive" ported head as
everyone with a grinder in his
garage was suddenly an expert at
cylinder head porting. John
found out that any attempt to
clean up the ports killed the
flow and port velocities
dropped. He scrapped that idea
and kept his well-proven chamber
modification, porting and valve
replacement system.
If you are looking for warm cuddly sheets we are clean out of them. We are tuners and you can buy all the trick parts in the world and a guy with a well tuned mild bike with a good power to weight ratio will kick your ass. Real world. Find a good tuner or become one. Look in the mirror.
Crystal Balls and Astrology
You win some, you lose some. Mostly we win. Like we always say it always depends on the tuner. This is not a parts changing business and we all know it's easiest to just change pipes and see what happens, but that's not science. The LSR 2-1 pipes, themselves, do not represent a "limit" as long as you choose the right pipe for your application. The rest of the equation is getting the parts and tuning to work together.
Just put the damn thing on the road, open her up, and see what she'll do. Let the metal scream.
Torque and Ruby Slippers
People get pissed at us when they ask for "numbers". We always tell them we "don't know" because after nearly 33 years of tuning and racing and designing we have seen too much and done too much to give any placebo answer. In fact it always depends on the bike and the tuner. No two bikes are alike. Maybe your bike was built on a Monday and they left a coke bottle in the gas tank (old Detroit wives's tale)...Some bikes are faster than others. Everyone believes their bike is "faster". It depends on the tuner and, these days, the bikes are more complicated. People change from chain to gear drives. They put on different cylinder heads. They switch cams. They add on tuning twiddle boxes. They tune, or the "shop" tunes. They "dyno" the bike...maybe even somebody rides the bike with instrumentation like our RSR Air Fuel Ratio Gauge.
People call us up then hang up when we tell them we don't know what their "gains" will be. We don't publish self-serving charts. We just take all the experience we have and build the best parts we can. People end up happy who buy the parts because they are well made and are designed to perform. We make different tube diameters and offer a wide range of systems for any particular bike so you will maximize your potential. There is no "One Size Fits All" at RB Racing.
People who don't buy the parts because we won't coddle them with assurances go elsewhere where Aunt Em will tuck them in and tell them what they want to hear.
Newer Dual Coat Black Ceramic Finishes
We have a lot more people looking for durable ceramic finishes and we think we have the best finishes on the market. In the late 70's and early 80's we tried all sorts of coatings and paints and even used porcelain on some of our products in the late 1980's. The newer ceramic finishes are tougher and we use both Polished Silver, and Semi-Gloss Black, to complement our usual chrome offerings. The newest "Turbo" Black finishes are a dual coat process that gives additional protection against scratches and nicks, providing two barriers against corrosion.
In more than 3 decades we have tried all sorts of black finishes: Kal Gard, VHT, Techline, and others. We also in the mid 1980's we even tried porcelain for awhile. It chipped and the heat distorted the parts. Most finishes will not survive over a long period unless they have a base coat to cushion rock strikes and scratches. The surface has to be perfectly prepared and most applications can fail if run too soon at elevated temperatures as they are typically baked at 450 to 500 deg F whereas the cure takes place at around 750 deg F. Lower temperatures will not cure the resins and they will fail once the bike is run. To get around this dilemma we have found the best solution is a 2500 Deg F Silver Ceramic cushion base coat and a secondary Black Semi-Gloss finish on top of this.
Dual Coat Black Ceramic
finishes are therefore expensive as
they involve a triple process. First the
parts are polished to remove any tooling
marks.Then the parts are zirconia media
blasted to prepare the surface. Then parts
are cleaned. The parts are base coated
with a 2500 Deg F Silver ceramic and
baked. The next day they are sprayed with
Black Ceramic and baked for a third time.
Three trips to the oven at 600 Deg F.
On our Dual Coat Black Ceramic LSR 2-1 Exhaust Systems the heat shields and heat shield clamps are ceramic coated with 2000 Degree F satin black ceramic finishes. These finishes resist carb cleaners and other chemicals. Our Silver Ceramic LSR 2-1s use silver ceramic coated heat shield clamps.
800 Horsepower LSR 2-1 Slash Cut
We're not really sure what a 2-1 has to do with Top Fuel Nitro motors but when Carl Pelletier asked us to make a collector for his top fuel 175c.i. PRP motor we whipped up a 4" diameter collector and sent him the tooling. Take a Tour of what it takes to run a top fuel bike. Doug Vancil's hard running Top Fuel Harley sponsored by Vance and Hines has a 2-1 that looks like one of their Pro Pipes so when Carl asked us to build one we made sure the collector area wouldn't restrict each of the 400hp explosions that were coming from each cylinder. Carl qualified 8th out of 32 bikes at the final Las Vegas meet and ran in the sixes at over 200 mph so the 2-1 probably didn't hurt anything. His best speed is 214mph with the 2-1 so it didn't seen to hurt anything. Top Fuel is pure insanity and is addictive as Heroin for those involved. Like they say " Gasoline is for washing parts...Nitro is for Racing!".
What does this have to do with your rubber-mounted V-Twin?...Not a damn thing! We are in the game however and we do our part.

and SA B2 Heads
We have been asked by customers to provide LSR 2-1 systems for S&S SA B1 and B2 four bolt heads as well as for the 126" and 145" S&S Tribute engines. Pictured above are our laser cut flanges and cnc machined venturis that we heliarc to the 2" primary tube for the S&S Racing heads. We make exhausts for both the S&S SA B1 and the S&S SA B2 four bolt cylinder heads with raised ports.
The 145" Tribute engines are 1" taller than stock and have special fixtures.
These days people have all sorts of expectations. They want to be loved. They want to be admired. They don't want their chrome to turn colors. They want "numbers". They want assurances. They want guarantees, warranties, trial periods, and return policies. They don't want the part, they just want everything that goes with their household baggage. It's all part of keeping everything nice and tidy and "best". Fear of rejection. Fear of making any decision.
We just come in and make the best parts we can and that's all there is to it. The rest of the equation is too complicated. There are plenty of people who will assure you till hell freezes over. We don't have time for this.
For those of you who do not understand that 1450 Deg F of exhaust flame front will discolor chrome don't order the parts, or just leave the bike on the trailer..or order the heat shields to cover up the underlying discoloration. Ceramic or chome the pipes get really hot and heat shields provide an air gap to protect and hide things.... Melted tennis shoes, burned pants. Air is the perfect insulator.
It isn't the old days anymore. People with $35,000.00 toys roll up in the screaming fetal position. Joy used to be a basket case that you could get running. Brave new world.
Angst
The agony of decision making can drive a poor consumer insane..."What is the best?"...".."How does it compare?"..."What will I get, what will I gain?"..."When can I get it?"..."Should I get a 2" or a 1 3/4" pipe".."Will the chrome blue?"..."Can I talk to someone who has one?"..."How long have you been in business"...""I've never heard of you"... "How black is the black?"..."Why haven't I seen these before?"..."My bike is at the builder and he has to have the pipe by Friday or I lose my slot!"..."Is the silver as shiny as chrome?"..."I have a wazoo998 cam and billet rocker boxes and a 280 rear tire...will your pipe work?"
Right brain, left brain. Fear of rejection. Fear of being different. Social standing. It's all too much for most people to deal with.
Look at the pictures, take the Red Pill, and start your journey. It's that simple.
If you wish avoid any decision and stay right where you are, just take the Blue Pill. If the journey for truth and power excites your spirit, take the Red Pill.
No Limp Dick Designs
Ever since Jesse James did his original Hell Bent pipes people have either copied them or tried to make whatever they were doing swoopy. If you are a slave to fashion then these might just suit your fancy. At RB Racing we build logical designs that work and leave the limp dick fashion trend to those who love to park and talk.
