Kooks Headers Long Tube Headers

Kooks Headers has been engineering high-performance exhaust systems since 1962, and their Long Tube Header lineup represents the definitive expression of that six-decade legacy. Purpose-built to replace restrictive factory exhaust manifolds, Kooks long tube headers are designed to maximize exhaust scavenging, unlock additional horsepower, and deliver improved torque across the entire powerband — from daily-driven street builds to dedicated track machines.

The long tube design extends primary tube length well beyond that of short tube or shorty headers, promoting stronger exhaust scavenging that produces meaningful, measurable gains in both horsepower and torque. Every design in the Kooks lineup is validated through real-world dyno and race testing, with a proven competition heritage that spans NHRA, IHRA, NMCA, NMRA, NASCAR, SCCA, and beyond.

Key Features:

• T304 Aircraft-Grade Stainless Steel Construction — Heavy-duty, crack-resistant tubing withstands extreme heat and high-horsepower conditions while providing long-term corrosion resistance
• Precision Mandrel-Bent Tubing — Smooth, radius-consistent bends maintain optimal exhaust gas velocity and unrestricted flow throughout each primary tube
• TIG-Welded for Strength — Expert-quality welds deliver leak-free, long-term performance through hard use and repeated heat cycling
• Dyno and Race Tested — Every header design is validated for real-world power gains backed by decades of professional motorsport development
• Catted and Catless Configurations Available — Options include catless designs for closed-course and off-road use, as well as EPA-certified Green Cat configurations engineered for street and highway emissions compliance without sacrificing performance
• Complete Hardware Included — Gaskets, mounting hardware, and oxygen sensor extensions are included where required for a straightforward installation
• Available as Standalone Headers or Connection Kits — Select applications pair headers with X-pipes, H-pipes, or Y-pipes to complete the mid-pipe section of the exhaust system
• Made in the USA — Manufactured at Kooks' ISO 9001:2015 certified facility in Statesville, North Carolina
• Limited Lifetime Warranty — Backed by a limited lifetime warranty to the original purchaser

Connection pipe options include X-pipes for high-RPM performance and race-focused applications, or H-pipes for increased low-end torque with a more refined, street-friendly exhaust note. Select applications also benefit from Kooks' exclusive Green Cat technology — high-flow catalytic converters engineered to maintain emissions compliance without sacrificing performance. Each set is precision-engineered for a specific platform, ensuring proper fitment and a direct-replacement installation experience.
