Kooks 3" Competition ULTRA X-Pipe (21703120) - 2014–2019 Corvette C7 6.2L
Unleash the full performance potential of your C7 Corvette with the Kooks 3" Competition ULTRA X-Pipe. Engineered for LT-powered Corvettes, this competition-only system is designed to maximize exhaust scavenging, sharpen throttle response, and deliver a crisp, aggressive exhaust tone that reflects true race-bred performance.
Built from premium 3" stainless steel, the ULTRA X-Pipe features a full-length Long Merge X-section that enhances exhaust pulse efficiency and improves overall flow compared to traditional X-pipe designs. Designed to connect to Kooks long tube headers and transition into the factory-style 2-3/4" rear exhaust, this setup creates a smooth, unrestricted exhaust path ideal for high-performance street/track builds. CNC-built for precision fitment, this system is intended strictly for competition or off-road use.
