Overview
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. Optionally, the famous Hooker Ceramic Thermal Barrier Coating is available.

Fitment Notes
- Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties.
- Hooker recommends using cast iron exhaust manifolds or old headers during your engine break-in period to avoid damaging your coated damage.
- The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up.
- Hooker does not recommend the use of header wraps as this will void the warranty.
- Hooker long tube headers do not come with header reducers.
- Some factory heads do not have a bolt hole in the end. Holes must be drilled and tapped to ensure proper seal.
