Super Trapp Quiet Mufflers: A 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. See the Model Selection Guide.
How it Works: The exhaust outlet is formed by stacking the individual diffuser discs to form a series of annular openings. The precise space 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 the engine's size. The exhaust noise will be minimized when the least number of discs is used with the optional resonators. As the exhaust flows out radially between the discs, the noise is first dissipated and then diffused over a 360 degree pattern. After leaving the discs, the exhaust path curves inward toward the centerline and is rapidly cooled by mixing with the surrounding air. Only 1/2" clearance is required between the disc's outer edge and any heat sensitive areas.
Model 3S MufflersAdapts to a wide range of engines 2 to 50 HP. Recommended for engines up to 10 HP where minimum exhaust noise is required, and for larger engines where space is limited.
Model 5S Mufflers:Designed for 10 - 200 HP engines. Recommended for engines from 10 HP to 100HP where minimum exhaust noise is required, and for larger engines where space is limited.
