Off-road systems need to be repacked after 6-8 hours of use, or after each Race. Repacking your muffler at the suggested intervals is essential for your exhaust to perform the way it was designed. Dirty packing restricts airflow from your motor, which results in a loss of power and degradation of sound. Repacking your muffler allows for freer airflow from your motor, which restores lost power and improves the exhaust sound.

Includes:


  • Premium Packing Material
  • Rivets
  • Rivet Band
  • Decals for Muffler sleeve and end-cap
  • Repacking Instructions

Brian Q. ★★★★★

The pre-cut lengths saved me so much time during a quick race-day swap, and the material packed in firmly without any messy loose fibers. My bike’s exhaust tone went back to that crisp, healthy note immediately after the repack.

Riley D. ★★★★★

The fiberglass came pre-cut and the instructions were clear, made getting my bike ready for the weekend hassle-free.

Lily I. ★★★★★

Had a race coming up and this kit saved me a trip to the shop. The pre-cut fibers fit perfectly inside the muffler shell, and the gasket material sealed everything back up tight. Quieted the bike down noticeably after the first ride.
