R77 Standard Muffler Repacking Kit by Yoshimura®. 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.
