This warranty only applies to the original owner of the exhaust. All of our exhausts are made from 100% 304l U.S.A. made stainless steel, under normal conditions they should last the lifetime of the car. Delta Motorworks reserves the right to deny this warranty under certain conditions. We are here to help, if you have a legitimate problem, we will try our absolute best to make it right.

Safety & Risks

Motor racing/aggressive driving is very hazardous and can cause death. We are not liable/responsible for your decisions. All exhaust systems are for off road use only.
