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. Competition Header, Tube Size 1.625" O.D., Collector Size 3" O.D., Port Shape: Same As Port, Ceramic Metallic Coating
Installation Notes
Breaking in an engine with ceramic coated Headers WILL result in damage to the coating and will VOID all warranties. Ceramic coated Headers require several heat cycles to fully cure before they will withstand extreme heat. Hooker recommends using cast iron exhaust Manifolds or old Headers to break in new engines to avoid coating damage. Please call Hooker tech service at 270–781–9741 for additional information regarding ceramic coated exhaust products.
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.
