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.
