Check your local laws and manufacturers information. NOTE: Installation of a new exhaust system may change your motorcycles fuel-air mixture requirements. Please consult the exhaust manufacturer directly with questions regarding any modifications that may need to be made during, or after, installing their product. If a jet kit or fuel processor is recommended, see the Intake/Fuel section. NOTE: Exhaust discoloration (blueing) is caused by engine conditions such as cam timing, fuel-air mixture, operating temperature, etc. See the Chems/Lubes section for products to help remove or prevent exhaust discoloration.
