Product Description


Yoshimura RS-4 Muffler Repack Kit

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 with a Yoshimura exhaust repack kit allows for freer airflow from your motor, which restores lost power and improves the exhaust sound.

Each kit includes:

  • 8 stainless steel rivets
  • 2 rivet bands
  • RS-4 end-cap decal
  • 950 gram silent sport premium muffler packing material
