Yoshimura Road exhaust systems need to be repacked every 7,000 - 10,000 miles. 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.

Customer Reviews (4.8 / 5 · 5 reviews)

Isabella ★★★★★

The fiberglass felt exactly the right density and length for my Yoshimura can—made the whole job straightforward in about an hour. My bike's exhaust note cleaned up nicely and lost that hollow sound it had started to get.

Harper ★★★★★

Bike sounds noticeably crisper after swapping the packing, and the kit had enough material to do the whole can without stretching it. I’d been riding past the 10,000-mile mark, so this brought the tone back to how it felt when new.

Timothy ★★★★★

Took about 20 minutes to pull the old packing out and stuff this in—the pre-cut material fit my can perfectly. My bike’s exhaust note is noticeably deeper and less tinny now, just how I like it.
