The only thing OEM bikes are missing is a Two Brothers Racing exhaust system. The M-2 exhaust systems will make the already impressive bike more impressive. Just by bolting on the M-2 exhaust system the rider will add HP and Torque while saving weight and giving it the sound that rider’s desire. Choose from Polished Aluminum or Filament Carbon Fiber Canisters with a Die Cast Magnesium Outlet.

The polished aluminum is a lightweight and strong material used extensively in the aerospace, automotive, and of course, motorcycle industry. 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 mirror polished finish. Ounce for ounce, aluminum is the best value of all the M series mufflers. As a rule the aluminum mufflers weigh about 8.3oz. more than Titanium or Carbon Fiber mufflers.

Two Brothers has been using Carbon Fiber in motorcycle mufflers since 1992. They are currently the only US Company to exclusively use Filament Wound Carbon Fiber (FWCF) on every carbon fiber muffler they sell. They draw on only the best high temperature resins, and control a proprietary lining system adopted from spacecraft, for additional heat resistance. The 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.
