All of the canisters perform and sound the same, they are simply different shapes

The shape and orientation is normally determined by our R&D department, based on a performance criteria check list

All aluminum systems include U.S. Forest Service approved spark arrestor

The exhaust tone produced by all of our 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

They all incorporate our exclusive technologies and premium construction materials

Our 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)
