Skunk2's high-flow racing 70mm test pipe for the S2000 is designed to dramatically improve engine performance and increase horsepower by significantly reducing exhaust flow restriction. Designed for off-road use only, Skunk2 Racing test pipes are manufactured from mandrel-bent, aircraft-quality, T-304 stainless steel and are precision TIG welded for precise fitment. Each Skunk2 racing test pipe features the appropriate sensor bungs, heavy-duty flanges, and its own stainless steel, acid-etched Skunk2 badge.
