Spark Arrestor without restrictive swirl baffles or fragile screens.

Easy to install, Multi-position Rated, Cooler Exhaust, Quiet and Compact, Optional Resonator for Maximum Silencing.

The exhaust outlet is formed by stacking the individual diffuser discs 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. 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.

As the exhaust flows out radially between the discs, the noise is first dissipated and then diffused over a quiet 360 ̊ pattern. After leaving the discs, the exhaust path curves inward toward the center line and is rapidly cooled by mixing with the surrounding air. Only 1⁄2" side clearance is required between the disc’s outer edge and any heat sensitive areas.
