Who better to trust your equipment with?

Mufflers are a filled with fiber packing that needs to be replaced at regular intervals depending on the rider and conditions. Mufflers with degraded packing often rob power and can quickly damage components of the exhaust system and/or the motorcycle.

Yoshimura offers Muffler Refurbish services that are performed at the factory by the same highly skilled technicians that assembled your muffler when it was new. Who better to trust your equipment with?

Exhaust System Maintenance

Yoshimura engineers and manufactures every one of our exhaust systems to perform to at the highest level. Whether on the commute or on the racetrack, our high-performance products are designed with longevity in mind. However, every exhaust system needs maintenance! Depending on the motorcycle (or ATV/UTV), where it is used and how it is being used, just like and engine, an exhaust needs to be maintained.

Yoshimura Exhaust Systems require very little maintenance.

Here are a few tips:

1. Use mild car/motorcycle soap to clean the exhaust system—do not use any abrasives or degreasers.

2. Clean your exhaust with metal/stainless polish every 1-2 months to retain the luster and remove dirt and grime.

3. Avoid contaminating exhaust surfaces when hot.

4.Your exhaust system will change color (blue, magenta, purple, and/or gold) due to heat; this is normal.

5. Keep all clamps, bolts and other fasteners tight as exhaust systems are susceptible to vibration damage.

6. If you ride in coastal regions or areas that use salt to control ice and snow, wipe the exhaust down after it cools to remove any possible salt residue, which can result in rusting.

7. If you are storing your motorcycle for the season, wipe the exhaust system down with rubbing alcohol before storage.8. Head pipes glowing (visible in normal light) may indicate an excessively lean condition that must be corrected.

Carbon fiber equipped exhaust components require special attention. The following addresses wear issues directly related to carbon fiber.

1. Keep all clamps, bolts and other fasteners tight. Carbon Fiber is very susceptible to vibration damage.

2. Keep all chemicals and solvents away from the carbon fiber, as they will damage the finish.

3. High temperatures will cause the resin in the carbon fiber to break down. Visual signs such as an amber hue in the resin may be early signs of heat damage to carbon fiber.

4. Upon seeing amber colored resin, discontinue use. The exhaust system needs to be inspected by a representative from Yoshimura, for repack, and/or repair. Continued use will cause component failure.

Stainless Steel is not rust proof but is less prone to rusting, staining and pitting; but it is prone to oxidation like all metals.
To maintain maximum sound and engine performance the muffler packing will need to be replaced at some time during the muffler’s life.

Yoshimura recommends repacking your muffler at least once a year. Failure to maintain the muffler packing may cause damage to the muffler and/or void the warranty. Regularly inspect the muffler body for discoloration, cracks, rattling, or other signs of wear caused by depleted muffler packing.

If muffler packing is determined to be depleted or worn, a Yoshimura muffler re-pack kit is highly recommended to restore the muffler to optimum maximum performance. Yoshimura offers a 3-5 day turn around (plus transit time) to inspect and refurbish used and damaged mufflers. 
Yoshimura recommends on all race exhaust systems, that all spring joints be safety wired. Recommended wire type 304/316 stainless steel with a .032” diameter should be used.
