NOTES:
Not all products are legal for sale or use on pollution controlled vehicles. Check your local laws and the manufacturer's information.

There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Discoloration (bluing) is the result of tuning characteristics, cam timing, carburetor jetting, overheating, etc., and is not caused by defective manufacturing. See Chems/Lubes for products that will help prevent or remove bluing.

Installation of a new exhaust system may change your motorcycle's 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 Fuel/Intake section.
