Two Brothers M series exhaust canisters feature the highest level of quality construction and are designed to be fully serviceable in the event of damage (replacement parts are available).
The exhaust tone produced by all of Two Brothers 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.
All of the canisters perform and sound the same, they are simply different shapes.
They all incorporate our exclusive technologies and premium construction materials.
The shape and orientation is normally determined by Two Brothers' R&D department, based on a performance criteria check list.
