Muffler Repacking: Details & Services

Do you remember when your muffler was last repacked?

If not, it's probably time...

Unlike their OEM counterparts, Yoshimura Road mufflers need to be repacked every 7,000 - 10,000 miles, while Off-road mufflers need to be repacked every 6-8 hours of use, or after 2 race motos, whichever comes first. Repacking your muffler at the suggested intervals is essential for your exhaust to perform the way it was designed. Heavy use conditions (long distance endurance riding or high RPM operation) will require more frequent maintenance.

Dirty packing restricts airflow from your motor, which results in a loss of power and degradation of sound. Periodic inspections of your exhaust system should be performed to look for signs of packing wear. Signs of packing wear include muffler and/or end-cap discoloration, hot spots, louder exhaust note, and yellowing of the Carbon Fiber. 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.

 

Yoshimura R&D offers Two Options for Muffler Repacking:

  • 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 3-5 business days, excluding shipping/transit times.

  • Alternatively, if you are comfortable repacking your own muffler, we sell all the materials as stand-alone products. We also provide an instructional how-to-video on proper procedure for repacking your muffler.
