M & C Series Canister Information (Road) |
|
The entire line of TBR M & C Series canisters feature the same
high level of quality construction and are designed to be fully
serviceable in the event of damage (replacement parts are available,
please call us), routine maintenance or the occasional
repack1. Two Brothers Racing’s
M & C series
spring-mounted slip-on canisters all feature our patented
and exclusive lightweight thinwall die cast aluminum one-piece inlets and
outlets. Our V.A.L.E.™ (patent pending) slip-on exhaust systems and flange-on systems feature CNC'ed aluminum inlets.
These special
designs provide for ease of maintenance as well as simplified
construction, which is what a premium performance product is all about!
The exhaust note produced by all of our Top Level™
exhaust systems is best described as being deep and throaty
without suffering from the shrill whine normally associated with
other manufacturer's straight through muffler canisters. |

We offer three distinct canister
shapes to choose from; small oval (C-2, C-7 or M-2), traditional round 4.5”
diameter (C4) and large oval (C-5 & M-5). All of the canisters perform and
sound the same, they are simply different shapes. They all incorporate
our exclusive technology and premium construction material. The
different exterior shapes allows you to choose the one that best fits
the style of your motorcycle. For instance most people prefer the C-2/M-2
(small oval) with smaller sized motorcycles (like 600cc machines)
while others prefer the C5/M5 (large oval) with larger sized motorcycles
(like 1000cc machines). For those who prefer round canisters we offer
the C4 (round). |

Our Patented
V.A.L.E.™ Attachment System |
|
 |
|
 |
|
V.A.L.E. = Variable Axis
Locking Exhaust The V.A.L.E.™ system is our revolutionary and patented method of
attaching our muffler canisters to the exhaust tube without the use
of springs or welding. Our V.A.L.E. systems allows the muffler
assembly - exhaust tube and canister - to be positioned perfectly on
the bike before all the mounting hardware is fully tightened. Once
the canister and exhaust tubes are properly aligned, the V.A.L.E.
assembly locks the muffler canister to
the exhaust tube assuring a perfect, leak-free fit. |

Exhaust Canister Materials

Regardless of sleeve material or shape,
all of our canisters perform and sound the same. We manufacture our
exhaust systems from different materials to allow you to best match
our canister to your bike. |

Aluminum is a very lightweight and strong
material used extensively in the aerospace, automotive, and of course,
motorcycle industries. Aluminum is a wise choice due to its excellent
strength to weight ratio, corrosion resistance, and clean look. We use
lightweight thin-wall .060” extruded 6061 aluminum alloy that is heat
treated to a T-6 condition for increased strength, durability, hardness,
and finish hold. After the aluminum has been heat treated, it is cut to
length and given a brushed satin finish. Ounce for ounce aluminum is the
best value of all our M & C Series mufflers. As a rule our aluminum
mufflers weigh about 8.3oz. more than Titanium or Carbon Fiber mufflers. |
We have been using Carbon Fiber in
motorcycle mufflers since 1992. We are currently the only US Company
to exclusively use Filament Wound Carbon Fiber (FWCF) on every
carbon fiber muffler we sell. We draw on only the best high
temperature resins, and control a proprietary lining system adopted
from spacecraft, for additional heat resistance. Our FWCF is
continuously wound over a precision machined mandrel for a 100%
seamless bond. The FWCF tube is then cured in a high temperature
autoclave oven for superior strength and heat resistance. These
crucial elements meld to form a precision lightweight muffler that
will perform as well as it looks. |
By weight titanium is one of the world’s
strongest readily available metals, making it ideal for our M & C series
mufflers. It is 45% lighter than steel with comparable strength, and
twice as strong as aluminum while being only 60% heavier. That’s right
titanium is HEAVIER than aluminum, but since it is twice as strong we
are able to use very thin (.024”) material to construct our Titanium
muffler. The result is a muffler that is about 8.3oz. lighter than our M
or C series aluminum mufflers. Titanium has become an industry standard
for motorcycle mufflers due to its durability, corrosion resistance,
lightweight, and factory look. |

This type of system replaces your existing “s-bend”
pipe and exhaust canister. Our s-bends are manufactured from .035"
thin wall stainless steel. We then polish them to a mirror finish.
We use only #304 stainless which will never rust.
After a few heat cycles the steel turns
a golden amber color which is the characteristic signature of high quality
stainless steel.
These systems not only adds horsepower but also can drop
significant weight from your bike. This type of canister can be mounted in
the original canister position or in a “high” mounted canister position
depending on the bike and our available applications. |
This canister bolts to your existing exhaust system directly
replacing your stock muffler. You retain your original headers and
"s-bend” pipe. This configuration not only adds horsepower but
also can drop significant weight from your bike.
Reinstallation of the stock
muffler, should the need ever arise, is very simple. This type of
canister can only be mounted in the original canister position
regardless of the bike. |
This system completely replaces your existing exhaust system. This not
only adds horsepower but also can drop significant weight from your
bike. We build our header systems as a complete unit.
Our finished system flows better at the
collectors, makes more power and does not vibrate on the bike.
Our superbike stainless steel headers are manufactured from .035" thin
wall stainless steel. We then polish them to a mirror finish2. The ductile
quality of stainless steel makes it possible to produce extremely light
and strong headers. We use only premium #304 stainless which will never
rust and after a few heat cycles will turn a golden amber color which is
the characteristic signature of high quality stainless steel. This type of canister can be mounted in the original position or in
a “high” mounted position depending on the bike and our available
applications.
Our chrome plated steel headers (available on select bike models) are
manufactured from .049" lightweight structural steel tubing which has been
polished, nickel plated and then chrome plated to the highest SAE J207
standard. All joints are MIG welded for strength and unparalleled style.

1Repack intervals vary depending upon riding conditions and type of bike.
2Stainless steel headers for some fully faired bikes will feature our mill
finish (unpolished) stainless steel headpipes but will have a highly
polished stainless steel "s-bend” connector pipe.
3Titanium canisters may shift color when exposed to elevated temperatures. This shift in color may occur at different rates resulting in color gradations ranging from blue, purple, red and even gold in some instances. |
