Off-road systems need to be repacked after 6 to 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.

RS-4 Repack Kit includes:

Stainless rivets (C3-RIVET x 8 qty.).
Rivet bands (LC4.5T x 2 qty.).
RS-4 end-cap decal (RS4-NB002 x 1 qty.).
Silent Sport Premium Packing Material (950 grams).

Good Product

I've been putting off repacking my muffler for a while. I purchased the Yoshimura packing and it was easy to install, just had to keep packing it in. Good sound and performance. Very happy.
