Important Exhaust Notes:

• Note: As with any new exhaust, you may need to change carburetor jetting or use of an aftermarket fuel injection control module for peak performance. • There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Blueing is caused by tuning characteristics, cam timing, carburetor jetting, overheating, etc. and is not caused by defective manufacturing. No refunds on exhaust pipes once motorcycle is started unless there’s a manufacturer’s defect. • DISCLAIMER: NOT LEGAL FOR SALE OR USE IN CALIFORNIA
