FAQ - How often should I re-pack my muffler?

Unlike their OEM counterparts, Yoshimura Road mufflers need to be repacked on occasion. Repacking your muffler after routine inspection reveals depleted muffler packing 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.

Deteriorated packing disrupts airflow from your motor, which results in a loss of power and degradation of sound absorption. 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 state of the art composite packing material for our mufflers, along with high-strength stainless steel rivets. We also include new badging to freshen up your muffler's appearance.
