Two Brothers M-2 Slip-On Exhaust
Two Brothers M-2. Small, vertical, oval canister (4.85”H x 3.75”W) is available with a aluminum high-polish finish, black carbon fiber (filament wound) or natural titanium matte-grey color. 2.25” stainless steel, power core. Packing consists of a first stage (stainless steel wool) and a second stage (high-temperature fiberglass). Slip-on comes with a billet, anodized, aluminum-inlet end cap. Flanged-on comes with a CNC, aluminum-inlet end cap. Teflon coated, die-cast, magnesium-outlet end cap. V.A.L.E.™ System Eliminates the need for springs resulting in a more secure mounting. Allows the muffler assembly to be positioned perfectly on the bike before all the mounting hardware is fully tightened. After perfectly aligned, the V.A.L.E. assembly locks the muffler canister to the exhaust tube assuring a perfect, leak-free fit.

Two Brothers M-2. The M-2 Slip-On exhaust canisters feature the highest level of quality construction and are designed to be fully serviceable in the event of damage, routine maintenance or the occasional repack. Two Brothers Racing’s M series spring-mounted slip-on canisters all feature patented and exclusive lightweight thinwall die cast aluminum one-piece inlets. The exhaust note produced by all Two Brothers 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.
The slip-on type of system replaces your existing “s-bend” pipe and exhaust canister. Two Brothers s-bends are manufactured from .035” thinwall stainless steel. They then polish them to a mirror finish. They use only #304 stainless which will never rust.
- Aluminum is a 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 mirror polished finish. Ounce for ounce, aluminum is the best value of all the M and C 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.
- By weight titanium is one of the world’s strongest readily available metals, making it ideal for the M 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 they are able to use very thin (.024”) material to construct the Titanium muffler. The result is a muffler that is about 8.30z lighter than the M or C series aluminum mufflers. Titanium has become an industry standard for motorcycle mufflers due to its durability, corrosion resistance, light weight, and factory look.
