Off-road systems need to be repacked after 6-8 hours of use, or after each Race. 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.

Contains all components to repack dual RS-9T mufflers.

Chloe E. ★★★★★

With two dirt bikes needing repacking, this 550g kit gave me exactly the right amount of material to do both mufflers without running short. The fiberglass felt consistent and packed evenly, which made the whole job straightforward.

Evelyn N. ★★★★★

I’ve repacked my muffler twice with this kit and the 550g portion is spot-on for a single service, no fiddly leftover bags to stash. The fiber feels dense and well-cut, so it tucked into the packing channels without fraying. It’s the first repack that’s held up through a full race day without the ex

The 550g pack gave me exactly enough to do both of my bikes back-to-back, which is perfect for race weekends. Repacking took about twenty minutes each and the exhaust tone is deep and solid again, no more tinny rasp. Just wish the instructions mentioned the 6-8 hour interval more clearly, but that's
