Kooks Headers Off-Road X-Pipe - Catless Mid-Pipe

The Kooks Headers Off-Road X-Pipe is a competition-grade, catless mid-pipe engineered for racers and performance enthusiasts who demand fully unrestricted exhaust flow. Designed exclusively for off-road and closed-course competition use, this X-pipe line is purpose-built to complement Kooks long tube header systems — eliminating catalytic converter restrictions and unlocking the full performance potential of a high-output exhaust setup.

The X-pipe crossover configuration creates a balanced scavenging effect between cylinder banks, equalizing exhaust pulses for measurable gains in horsepower, torque, and throttle response across the full RPM range. Compared to traditional H-pipe designs, the X-pipe layout minimizes resonance and delivers an aggressive, race-inspired exhaust tone that defines serious competition builds.

Key Features:

• Catless Off-Road Design: Removes catalytic converter restriction entirely for maximum exhaust flow and an unrestricted, aggressive exhaust tone purpose-built for competition
• X-Pipe Scavenging Configuration: Synchronizes and balances exhaust pulses between cylinder banks for optimized power extraction throughout the entire RPM range
• T304 Aircraft-Grade Stainless Steel: Delivers superior corrosion resistance, crack resistance, and long-term durability under the sustained demands of high-output competition use
• Mandrel-Bent Tubing: Maintains a consistent inner diameter through every bend for unrestricted exhaust flow and maximum performance output
• Precision TIG-Welded Construction: Leak-free joints built to withstand the rigors of sustained, high-output competition driving
• Engineered for Kooks Long Tube Headers: Purpose-matched to integrate seamlessly with Kooks header systems for a complete, optimized exhaust solution
• Dyno and Race Tested: Every product is tested for proven, real-world power gains before leaving the facility
• Limited Lifetime Warranty: Backed by Kooks' limited lifetime warranty to the original purchaser
• Handcrafted in the USA: Built by skilled technicians across three generations of family ownership to the exacting standards trusted by professional racers worldwide

Kooks Headers has been the benchmark for American high-performance exhaust manufacturing since 1962, earning championships and records across NHRA, IHRA, NMCA, NMRA, NASCAR, NASA, SCCA, and beyond. Independently owned and operated, Kooks designs and builds every product in the USA. The Off-Road X-Pipe line carries that legacy forward, delivering competition-grade engineering for the strip, track, and closed-course use.
