Plus, they can stand up to the heat, literally and figuratively. They're available in 4 and 5 in. disc sizes. Their body diameter is 3.5 in., and tapers up to a 4 in. opening (on the 4 in. discs) or 4.5 in. diameter, up to a 5 in. opening (on the 5 in. discs). They also have a U.S. Forest Service approved spark arrestor design (T-102).

Finish on exhaust is very poor, when hot paint literally rubs off of canister. Kit lacks strap for mounting during motorcycle applications. Otherwise product performs as expected from Supertrapp.
