Designed to match our race headers for 1998-02 LS1 Camaro/Firebird, this Y-Pipe is made of mandrel-bent 3'' 16-gauge 304 stainless steel tubing for maximum flow and power. This direct replacement part for the stock Y-pipe and catalytic converters fits under the chassis without flow-reducing dents, unlike our competitor's Y-pipe. It has better ground clearance than other Y-pipes. For competition use only.
