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.

Customer Reviews (4.6 / 5 · 5 reviews)

Claire D. ★★★★★

Opened the box and was pleasantly surprised by the quantity—it’s a generous 700g pack, which should easily handle at least two repacks on my bike. The material feels dense and high quality, and it seems like it’ll hold up well through a race weekend. Exactly what I needed to keep things running stro

Joshua ★★★★★

Weighing it, you can tell the 700g kit is dense with quality fiber. It packed into my can perfectly and the bike sounds crisp and deep again.

Amelia ★★★★★

Opened the muffler after a race weekend and the old packing came out in chunks, but this kit’s fiberglass was dense and even, so the repack took half the time I expected. The 700g weight is spot on for a standard silencer, and the new fill held up through a full day without sagging.
