Note: Please see local regulations to confirm noise and emission compliance.

Important Exhaust Notes:

• Note: With any new exhaust, we recommend changes to carburetor jetting or use of an aftermarket fuel injection control module.
• 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 the motorcycle is started unless there's a manufacturer's defect.
• Flanges and retaining rings are not included with most aftermarket exhaust for Evolution and Twin Cam models. Re-use your existing hardware, or purchase replacement hardware.
