Designed as an economical way to convert your stock muffler into a U.S.F.S. approved spark arrested muffler. When the spark arrestor screen is not required—such as at the MX track—simply remove three machine screws and take out the screen. It’s as simple as that. Each end cap is machined out of solid 6061 aluminum and installs quickly and easily. Features:
- The Pro Moto Billet spark arrestor caps fit the stock exhaust pipe.
- End caps are anodized to match the factory color of the bike.
- This spark arrestor end cap uses a removable, USFS-approved, screen-type spark arrestor.
- Engraved as USFS approved.
- All hardware is provided, but you will need a drill and a rivet gun.
- 96db silent inserts are available for most models.
Help keep riding areas open by adding a Silent or Ultra Silent Insert to your spark arrestor end cap. The Silent Insert reduces the exhaust note by 3–5 decibels and the Ultra Silent by 4-6 decibels. Both result in more acceptable sound intensity levels.
