Kooks 3" x 2-1/2" SS Competition X-Pipe (21503101) - 1997–2004 Corvette C5 5.7L
Maximize exhaust flow and race-inspired sound in your C5 Corvette with the Kooks 3" Competition Only Stainless Steel X-Pipe. Designed for high-performance LS1 and LS6 applications, this X-pipe delivers reduced backpressure, improved scavenging, and a sharper, more aggressive exhaust tone ideal for track-focused builds.
Constructed from premium stainless steel, this system features a true 3" inlet transitioning to 2-1/2" OEM-style outlets for seamless integration with factory-style cat-back systems. The 3-piece design allows for improved fitment and easier installation, while the competition-only configuration removes catalytic converters for unrestricted exhaust flow. This X-pipe is engineered to work specifically with Kooks long tube headers.
