Skunk2’s high-flow Racing Test Pipe for the '00-'09 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.

Designed for off-road and racing applications where a catalytic converter is not required.
O2 sensor bung thread pitch: M18 x 1.5.
