At DMG Motorsports, we present the Yoshimura Alpha Premium Muffler Repack Kit (REPACK-ALP-ADV) — the factory-correct service kit designed to bring your tired Yoshimura Alpha Premium muffler back to like-new performance. Over time, packing material inside your slip-on or full exhaust breaks down and gets dirty, and that's not just a cosmetic issue. Repacking your muffler at the suggested intervals is essential for your exhaust to perform the way it was designed, since dirty packing restricts airflow from your motor, which results in a loss of power and degradation of sound. This kit supplies everything needed to do the job right and get your bike sounding and running like it did on day one.

Yoshimura recommends servicing your muffler on a regular schedule to keep performance where it belongs, noting that Yoshimura Road exhaust systems need to be repacked every 7,000 to 10,000 miles. Repacking with genuine Yoshimura material restores that crisp exhaust note and the horsepower gains your Alpha Premium system was built to deliver, since repacking your muffler allows for freer airflow from your motor, which restores lost power and improves the exhaust sound. This kit is built specifically for Alpha Premium mufflers, and buyers should note that it is designed to only fit Alpha Premium mufflers and does not fit Alpha-T tapered mufflers.
