Hooker Competition headers offer the best value in the high performance header market. Designed for the value-conscious buyer, Hooker Competition headers offer premium features at a very competitive price. Made of durable 16 gauge mild steel tubing, the Hooker Competition header design utilizes a long transition collector to reduce back pressure and increase exhaust flow. A perfect sealing surface is assured with the 5/16" machined flanges, with welded O-ring seals. Experience has proven that this flange size is ideal to maintain header integrity and be pliable enough to seal each exhaust port. Tubing is mandrel-bent to maintain metal strength and provide consistent tube diameter at radii to maximize performance. Hooker Competition headers have a standard finish that features a heat-cured, high-heat-resistant paint.

• Tuned-length primary tubes for better performance
• Mandrel-bent tubing for smooth exhaust flow
• Light weight & sturdy 16 gauge tubing
• Long transition collector for decreased back pressure
• 5/16” machined flanges for a perfect seal
• Industry’s best welds for durability
• Designed for easy, trouble-free fit
• All necessary hardware included for a complete installation
