Boost Logic’s M157 Stainless Steel Downpipe and Midpipe kit offer superior airflow and heat management over the OEM design. Thick one piece cast flanges not only resist warping, but can hold up to the toughest abuse that would normally crack a thinner OEM design. By replacing the restrictive OEM parts with 3″ mandrel bent tubing this exhaust not only increases performance, but also dramatically increases the definition and tone of the exhaust. All our M157 downpipes come ceramic coated to help keep the heat inside the piping, helping to reduce engine bay temperatures and improve exhaust velocity. This kit comes with all stainless steel mounting hardware as well as stainless steel heat shields and v-band clamps.
