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.

What Sleeve Material Should You Get?

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.

Polished/Brushed Aluminum

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.

Carbon Fiber

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.

Titanium

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.

What is M2R?

The Revolutionary Two Brothers Racing M2R Quick-Pack Canister- featuring REM™(Ridiculously Easy Maintenance)

Two years in the making, the all new Two Brothers Racing® M2R REM Exhaust Canister is a quantum leap forward in motorcycle exhaust technology.
Silencer re-packing on the M2R can now be completed in minutes, without removing the muffler from the bike and without having to drill out and replace pop-rivets. 
An industry first...and long overdue.

The Goal: A racing motorcycle is all about more power and less weight and an exhaust system is the first step towards accomplishing that goal. The ultimate racing exhaust system has no muffler at all, as seen in F1 and MotoGP. In the real world however mufflers are required so the motorcycle does not exceed noise level restrictions. No performance muffler makes more power and has less weight than the tried and proven straight-through perforated core design. This is the reason that race motorcycles use them. And the porous fiber-mineral packing around the perf-core is what makes it a muffler, attenuating the sound output.
 
The Problem: The packing material around the perf-core becomes brittle after repeated heat cycles, once brittle it loses its ability to dampen sound. Furthermore it eventually brakes down and is blown out by the exhaust gases through the core’s perforations. Periodic repacking of a performance exhaust system is essential to maintain peak power output and eliminate excessive noise. A blown-out muffler loses as much as 50% of the power gain it had when new and the resulting noise generated is offensive and most often, illegal.
 
The Solution: The new Two Brothers Racing M2R REM muffler is the byproduct of their depth and understanding of a motorcycle performance exhaust system. TBR understands all too well the realities of keeping up with the essential and unnecessarily difficult maintenance required on a racing muffler.  Our new and patent pending design, is revolutionary. Now riders can —regardless of their mechanical ability— tackle a muffler re-pack job quickly and easily.
The secret is in the M2R’s modular system. Muffler re-packing is done from the outlet end of the canister while the muffler is still on the bike. Behind the familiar TBR Magnesium end cap and under their unique P-series power tip is a proprietary core lock system that holds the outer end cap, muffler core and packing in place. Easily removed with the included tool, the spent packing slides out and a new, press-formed packing cartridge slides right in.
