The warranty is void if the performance exhaust products are not installed properly on the vehicle for which it is designed.

    Warranty does not apply to any exhaust product which has been installed on any commercial or racing vehicle or which has been improperly installed, altered, or subjected to misuse or damage from accidents.

  • Cost of labor and any additional parts required to complete installation of a replacement product are not covered by this warranty.

    Catalytic Converters are emission control devices which are designed to last the life of the vehicle and do not normally require replacement. Furthermore, if the vehicle is properly used and maintained, original converters are covered by the emission control warranty for 8 years or 80,000 miles. Federal law prohibits repair businesses from replacing these devices except under certain limited circumstances. In order to verify that proper circumstances exist, the owner of the vehicle on which such repairs are made and a facility representative must sign the required statements on the warranty card. To avoid failing a warranty audit, please follow the instructions to ensure the new cards are filled out correctly and distributed accordingly.
