SuperTrapp 3S Series Spark Arrestor Small Engine Mufflers Product Group

SuperTrapp 3S Series Spark Arrestor Small Engine Mufflers

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.
