Our performance down pipes replace the restrictive stock exhaust with high flow, 200 cell sport catalytics for improved performance, reduced back pressure, greater exhaust gas volume and better sound.

Combined with RENNTECH's ECU software our down pipes create an incredible sound with performance to match.

Our down pipes mate perfectly with the stock exhaust systems and include all necessary mounting hardware and clamps. High-strength 304 stainless steel construction with high flow, 200 cell sport catalytics ensure lasting quality and a rich, consistent sound.
