Yoshimura Road exhaust systems need to be repacked every 7,000 - 10,000 miles. 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.

Aurora ★★★★★

Just packed my Yoshimura exhaust after hitting 9k miles, and this kit has the exact fiberglass density to bring the sound back crisp without getting too loud. The prepacked strips fit snugly around the core, way easier than cutting my own material.

James O. ★★★★★

My bike's exhaust had been sounding a bit flat around 8,000 miles, and this kit's pre-cut fiberglass sleeve made the whole process straightforward without needing extra cutting. The included oil and instructions were spot-on for getting the old packing out cleanly.

Robert R. ★★★★★

I was able to do the repack myself in under an hour—the pre-cut strips made it much easier than expected. My bike’s exhaust note is noticeably cleaner and deeper now after 8,000 miles.
