The Yoshimura Premium Muffler Repack Kit is the replacement packing material for R-77 mufflers, supplied cut and shaped for the canister rather than as bulk material.
Exhaust packing burns out gradually from the inside, and it does so slowly enough that most riders never register the change. The bike simply gets louder over a season or two, the note turns harsh, and the canister begins to drone at cruising speed. A repack puts the sound back where it started.
It also protects the hardware. Once the packing is gone, the perforated core takes the full heat and pressure pulse of the exhaust, and a core costs many times what a repack kit does.
Fits Yoshimura R-77 mufflers. Note that the R-77 and R-77M take different kits — confirm which canister you have before ordering, as packing is cut to specific dimensions and is not interchangeable.
