PLEASE NOTE:

These downpipes do not use EPA-compliant GESI catalysts. As a cost-effective alternative to our GESI catted variant, these downpipes instead utilize three-way, EURO5 rated, 400-cell catalysts. 

We cannot guarantee catalyst inefficiency related codes (CEL) will not be present after install. 

These parts are designed for OFF ROAD / RACE USE ONLY. We recommend running a tune on your vehicle for optimal results.
