Kooks 3" Catted Stainless X-Pipe (21603211) - 2009–2013 Corvette C6 6.2L

Upgrade your C6 Corvette’s exhaust system with the Kooks 3" Catted Stainless Steel X-Pipe, designed to deliver improved exhaust flow, sharper throttle response, and a more aggressive exhaust note while retaining catalytic converters. Engineered specifically for LS3-powered Corvettes, this X-pipe strikes the ideal balance between performance and street-friendly sound.

Constructed from premium stainless steel, this system features a 3" inlet that transitions to 2-1/2" OEM-style outlets for seamless connection to factory-style cat-back exhaust systems. The revised 3-piece X-section and Torca swivel-seal connections provide improved alignment, flexibility, and leak-free fitment when paired with Kooks long tube headers. Equipped with standard race catalytic converters, this setup is intended for naturally aspirated applications only.
