If not, it's probably time...

Unlike their OEM counterparts, Yoshimura Road exhaust systems need to be repacked every 7,000 - 10,000 miles, while Off-road systems need to be repacked after 10-15 hours of use. 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.

At Yoshimura, we use advanced space-age fiberglass packing material for our mufflers, along with high-strength stainless steel rivets. We also include new badging to freshen up your muffler's appearance.

First, we offer muffler repacking as a service. Simply call one of our expertly-trained sales representatives, who will assist you with cost and shipping information, as well as answer any other questions you may have. Once your muffler arrives at our factory, our team will remove and dispose of your old packing material and replace it with our proprietary space-age fiberglass packing material. Turn-around time is approximately 2 business days, excluding shipping/transit times.

Alternatively, if you are comfortable repacking your own muffler, we sell all the materials as standalone products. We also provide a free instructional how-to video on how to repack your muffler.

To schedule a repacking service or to purchase packing materials and rivets, please contact our sales team:
