Big Gun Powersports Spark Arrestors

Big Gun Exhaust USFS Spark Arrestors

Big Gun Exhaust USFS spark arrestors keep sparks from flying out of the exhaust and setting things on fire. The U.S. Forest Service requires that a screen be inserted into the exhaust outlet to prevent carbon buildup from becoming ignited and shooting out. They're compatible with all Big Gun Exhaust systems, include the spark arrestor and spacer ring, and install in minutes. Notes: * If you are just using the spark arrestor without a quiet insert, you must use the spacer ring * Either the spark arrestor or spacer ring is needed for the proper installation of a Vortex or Vortex 2 insert * Use Loctite on all screws when installing and check periodically to ensure they're tight
