KIES MOTORSPORTS, LLC — TERMS AND CONDITIONS OF PURCHASE AND SALE

🛑 OFF-ROAD / RACE USE ONLY & WARRANTY TERMS

These parts are for OFF-ROAD / RACE USE ONLY. They are not USA 50-state legal and are not legal for street use in some countries.

CAT Warranty (Valid for Two Years): Warranty claims are only approved if a Check Engine Light (CEL) is explicitly triggered due to the catalytic converter. If this occurs, we will provide a replacement downpipe free of charge; however, the customer is fully responsible for all domestic and return shipping fees. The old unit must be returned and confirmed received by the original dealer before the replacement is shipped.

We've just finished the very first sample of our catted downpipe, and we pushed hard to make it happen fast! With U.S. emissions regulations in mind, we decided to move away from a catless option.

This setup runs a 3.5" diameter right off the turbo outlet, paired with a massive 5" high-flow cat to keep exhaust flowing smoothly. We're using a 300-cell metal cat, and yes — NO CEL GUARANTEE! Bringing even more performance & exciting exhaust sounds to your vehicle.
