Kooks Headers 45-Degree Mandrel Bent Exhaust Tubing - T304 Stainless Steel

Kooks Headers has been the leader in high-performance exhaust manufacturing since 1962, and their 45-degree mandrel bent exhaust tubing line reflects that same commitment to precision and quality. Engineered for professional fabricators and serious performance builders, this tubing line delivers the geometric accuracy, material integrity, and race-proven reliability that demanding custom exhaust work requires.

At the core of this product line is true mandrel bending technology. Unlike conventional crush bending, mandrel bending preserves a consistent internal diameter throughout the entire curve — eliminating flow restrictions, reducing turbulence, and promoting efficient exhaust gas scavenging for improved engine performance. Each bend features a precisely engineered Center Line Radius (CLR) for accurate, repeatable results across any fabrication application.

Key Features:

• T304 Aircraft-Grade Stainless Steel — Premium material delivering superior corrosion resistance and the ability to withstand extreme exhaust heat cycle after cycle
• CNC Mandrel Bent — Maintains a consistent internal diameter throughout each bend for unrestricted exhaust flow and maximum scavenging efficiency
• Precise Center Line Radius (CLR) — Engineered to exact specifications for accurate, repeatable fitment in professional-grade fabrication work
• Multiple Diameters and Gauges Available — A broad range of options to suit custom header builds, full exhaust system fabrication, and repair work across a variety of applications
• Dyno and Race Tested — Designed and validated for maximum power output in real-world performance environments
• Handcrafted in the USA — Manufactured domestically by Kooks' skilled craftsmen, applying the same attention to detail found in their world-class header systems
• Limited Lifetime Warranty — Backed to the original purchaser, reflecting Kooks' confidence in their materials and workmanship
• Race-Proven Heritage — Trusted by championship-winning teams across NHRA, IHRA, NMCA, NMRA, NASCAR, NASA, SCCA, and many other sanctioning bodies

Whether building custom headers from scratch, routing a complete exhaust system, or performing precision repairs, Kooks 45-degree mandrel bent tubing delivers the consistency and quality that professional fabricators demand. Backed by three generations of family craftsmanship and an independently owned legacy of motorsport success, this tubing line is built to perform on the street, the strip, and everywhere in between.
