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

Grace J. ★★★★★

Bought this for my RMZ after a race weekend, and it fit the stock muffler perfectly. The 750g kit was exactly what I needed to get the packing refilled without any leftover material — a solid 5-star for simplicity.

Chloe ★★★★★

Repacked the muffler after a full race weekend and the difference in sound was immediate—tight and crisp instead of the dull blow-by I had before. The 750g kit gave me exactly enough to do the job right, and the instructions were clear enough for a first-timer.

Nicholas W. ★★★★★

Pulled the old packing out after a dusty weekend race and this 750g kit had everything I needed to get the exhaust back to sounding tight. The repack process took me about 20 minutes, and the muffler feels noticeably quieter on the trail now. Just glad I stocked up before the next event.
