Kooks 21613121 Stainless 3" Competition ULTRA OEM-Connect X-Pipe for 2006-2013 Corvette C6 ZO6/ZR1

The Kooks 3" Stainless Competition-Only ULTRA X-Pipe from Accesspeed will unleash the full potential of your 2006–2013 Corvette C6 Z06 or ZR1. The Kooks Competition-Only ULTRA X-Pipe is 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 top-end power, and deliver the unmistakable X/H-inspired tone Corvette enthusiasts love.

Crafted from premium 3" stainless steel and built for maximum flow, this system pairs only with Kooks Long Tube Headers. When combined, they create a free-breathing, track-proven exhaust path that sharpens throttle response and amplifies the raw character of your naturally aspirated or supercharged V8. Expect a crisp, exotic edge on acceleration with the deeper mid-range resonance associated with blended X/H systems.
