Pro Circuit Replacement Cartridge Muffler Packing

Pro Circuit silencer packing kits are available in multiple sizes for all four-stroke & two-stroke exhausts. Each kit includes enough packing material to restore your bikes exhaust and keep it performing as intended from the factory. Pro Circuit recommends re-packing your exhaust every 10-15 hours. With that being said, service intervals can vary drastically between riders and riding conditions. Some riders can go a full year without needing to repack their muffler while more aggressive riders can destroy new packing in as little as a few rides.
