  NOTE: There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Discoloration (blueing) is the result of tuning characteristics, cam timing, carburetor jetting, overheating, etc., and is not caused by defective manufacturing.
  
  NOTE: Installation of a new exhaust system may change your motorcycles fuel-air mixture requirements. We recommend purchasing a fuel management tuner such as Power Commander V
