We accept returns within 14 working days, you must confirm in writing prior to return and quote our RMA number. In the event an item is supplied which is not as described, we will accept return and refund the cost of shipping the item. Warranty: 12 month warranty. This does not include any manufacturer's warranty. The warranty applies to PARTS ONLY, and does NOT include labour. Faults must be reported within 30 days of becoming apparent. We will replace or repair the item free of charge EXCLUDING postage on return of the failed unit. This warranty shall not apply to any defect arising from normal wear and tear or neglect, misuse, improper storage or unauthorised repair. Exhaust catalytic converters that have been fitted will NOT be accepted for return. Faulty catalysts must be accompanied by an emission report. Unfortunately we have had people buy a catalyst because their vehicle has failed the test, then fitted the new unit in order to pass the test. They have then refitted their old catalyst and attempted to send the new one back as faulty.
