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 lubrication products for products that will help prevent or remove bluing.

For the best performance, a free-flowing air cleaner and carb re-jet kit or adjustable fuel management system is recommended with this pipe. Dennis Kirk recommends a speed's performance speedyflow air cleaner for most models. See 18-3336 for 93-99 EVO carb models or 18-3337 for all Twin Cam models
