Kooks 3" Competition Only X-Pipe (21603101) - 2005–2008 Corvette C6 6.0L / 6.2L
Maximize exhaust flow and unleash a raw, race-inspired sound in your C6 Corvette with the Kooks 3" Competition Only Stainless Steel X-Pipe. Designed for LS2 and early LS3 applications, this X-pipe improves scavenging and reduces backpressure for stronger top-end performance while delivering an aggressive exhaust tone.
Constructed from premium stainless steel, this competition-only X-pipe features a 3" inlet design that transitions to 2-1/2" OEM-style outlets for compatibility with factory-style cat-back exhaust systems. The updated 3-piece X-section and Torca swivel-seal connections provide improved alignment, flexibility, and leak-free fitment when paired with Kooks long tube headers. This system removes catalytic converters and is intended for off-road or race-use applications.
