Kooks 3" Catted Stainless X-Pipe (21603201) - 2005–2008 Corvette C6 6.0L / 6.2L
Enhance exhaust flow and sound in your C6 Corvette while retaining catalytic converters with the Kooks 3" Catted Stainless Steel X-Pipe. Designed for LS2 and early LS3 applications, this system improves scavenging and throttle response, delivering a sharper, more aggressive exhaust note without going fully competition-only.
Constructed from premium stainless steel, this X-pipe features a 3" inlet that transitions to 2-1/2" OEM-style outlets for seamless connection to factory-style cat-back exhaust systems. The updated 3-piece X-section and Torca swivel-seal connections provide improved alignment and leak-free fitment when paired with Kooks long tube headers. This system uses standard race catalytic converters and is intended for naturally aspirated applications only.
