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 enough components to service one RS-9D muffler:

• Stainless steel rivets
• Rivet bands
• End-cap decal
• Silent sport premium muffler packing materials
