R-77 Premium Muffler Repack Kit

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.

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.

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.
