SuperTrapp™ Spark Arrestor

SuperTrapps’s patented “diffuser disc” design cuts noise and traps hot sparks in a system that is quieter, smaller and lighter than any other spark arrestor or compact muffler.

The exhaust outlet is formed by stacking the individual diffuser to form a series of annular openings. The precise spacing between the discs provides a barrier against noise and sparks without restricting the exhaust flow while the number of diffuser discs required is proportional to engine size. The exhaust noise will be minimized when the least number of discs is used.

SuperTrapp is the only U.S.D.A Forest Service Approved Spark Arrestor without restrictive swirl baffles or fragile screens. Hot sparks are propelled directly into the collection chamber (end cap) by the natural exhaust flow momentum. The .23” spacing between the discs gives back-up protection should be chamber fill to capacity.
