This is the optional Resonator for the SuperTrapp 3S Series Spark Arrestor Mufflers (sold separately). Adding this resonator to a 3S Series muffler will reduce noise by 3 to 5 dbA without affecting power. Further noise reduction can be achieved by removing diffuser discs, but this will cause a loss in power.

SuperTrapp mufflers are the only USDA Forest Service Approved spark arrestors that do not rely on restrictive swirl baffles or fragile screens. Sparks are funnelled into a collection chamber in the end cap, while exhaust gases exit between special diffuser discs. Even if the collection chamber filled to capacity, the small 0.023" gap between the discs still provides a back-up layer of spark protection.

The 3" diameter SuperTrapp 3S Series muffler is recommended for engines up to 10 HP, but it can also be used on engines up to 50 HP where compact size is a greater concern than noise reduction.

Resonator includes an extended center retaining bolt.

Note: The SuperTrapp 3S Series has been discontinued. Remaining stock on hand is the last available. When they sell out, we will not be able to get any more.
