The Hi-Flo Downpipe with Integrated Catalytic Converter is of the highest quality and all stainless steel construction. Upgrading the restrictive factory downpipe with this unit is the best way to increase performance; boost spike increased about 1.5 psi due to reduced back pressure, a deeper exhaust sound by maximizing flow, reducing underhood temperature and eliminating unnecessary restrictions all in a high-quality package.
