Kooks Headers Off-Road Y-Pipe

The Kooks Headers Off-Road Y-Pipe is a race-proven, catless mid-pipe solution engineered to maximize exhaust flow and unlock the full performance potential of your engine. Designed to bridge Kooks long tube headers to the remainder of the exhaust system, these off-road Y-pipes eliminate the flow restrictions imposed by factory components to deliver real gains in horsepower, torque, and exhaust tone.

Key Features:

• Catless off-road design — removes catalytic converter restrictions for unrestricted exhaust flow and the most aggressive exhaust note possible
• Mandrel-bent tubing — maintains a consistent interior diameter through every bend to maximize exhaust velocity and minimize back pressure
• T304 stainless steel construction — crack-resistant, aircraft-grade stainless delivers exceptional heat resistance and long-term durability
• TIG-welded joints — precision welds ensure leak-free performance under demanding race conditions
• Direct-fit OEM outlet connection — bolts directly to factory exhaust connection points using stock hardware; no cutting or welding required
• Designed for use with Kooks long tube headers — engineered specifically to integrate with Kooks header systems for a complete, optimized exhaust solution
• Dyno and race tested — designed and validated for maximum power output in real-world performance environments
• Handcrafted in the USA — proudly manufactured by a three-generation family company with over 60 years of exhaust expertise
• Limited lifetime warranty — backed by Kooks' limited lifetime warranty to the original purchaser

Since 1962, Kooks Headers & Exhaust has been the benchmark for high-performance exhaust components, earning championships across NHRA, IHRA, NMCA, NMRA, NASCAR, SCCA, and other premier motorsports organizations. Every Off-Road Y-Pipe reflects that race-winning heritage — built to the same exacting standards that have made Kooks the trusted choice of serious performance enthusiasts and professional racers alike.
