Starting from the ground up, the M-7 exhaust canister was designed exclusively to meet the brutal demands of off-road performance. Each model is engineered specifically for each application, with hours of track and dyno testing; proving the M-7 achieves the absolute top level in offroad performance requirements.

Using only the highest quality materials available, the M-7 is built to last. Two Brothers Racing exclusive use of a stainless steel spiral perforated core, designed further enhances the sound attenuation properties of the muffler, while still increasing the HP and torque of each model. The M-7 also features a removable Teflon coated magnesium end cap for easy removal of the Screen Type spark arrestor or for adding one of the optional sound suppressor sound tips. Allowing you to lower the decibels from 3 to 8 dbs depending on which P-Tip you choose.

Note: All canister materials deliver equal performance with their own unique look.

Carbon Fiber
Two Brothers Racing has been using Carbon Fiber in motorcycle mufflers since 1992 and 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 utilize 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.

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. Two Brothers Racing uses lightweight, thin-wall .060 extruded 6061 aluminum alloy that is heat treated to a T-6 condition for increased strength, durability, hardness, and finish durability. After the aluminum has been heat treated, it is cut to length and brushed to resist scratching from roost. Ounce for ounce, aluminum is the best value of all our M Series mufflers. As a rule, our aluminum mufflers only weigh about 8.3oz. more than our Carbon Fiber mufflers.
