3" SS H.O. GREEN Catted ULTRA X-Pipe. 06–13 Corvette C6 Z06/ZR1. Connects to OEM

3" Stainless High Output GREEN Catted ULTRA X-Pipe

Unleash the full potential of your 2006–2013 Corvette C6 Z06 or ZR1 with a Kooks H.O. GREEN Catted ULTRA X-Pipe engineered exclusively for LS7 and LS9 performance. Designed to integrate with 3" OEM-style exhaust systems, this upgraded ULTRA X configuration uses a full-length Long Merge to improve scavenging, enhance overall exhaust efficiency, and deliver the unmistakable X/H-inspired tone Corvette enthusiasts love.

Equipped with H.O. GREEN catalytic converters, this system refines exhaust character while preserving the aggressive personality expected from a ULTRA X layout. Expect a crisp, exotic edge under acceleration complemented by a deeper, more composed mid-range resonance, providing a balanced, performance-driven sound that stands out without overwhelming rasp.

Crafted from premium 3" stainless steel and built for high-performance applications, this system pairs only with Kooks Long Tube Headers. Together, they create a smooth, unrestricted exhaust path that sharpens throttle response and elevates the driving experience of your LS-powered Corvette.
