Hooker Competition Headers offer the best value in the high performance header market. Designed for the value–conscious buyer who is running either a “stock” or “mildly–modified” engine, 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.
Competition Header, Tube Size 1.625" O.D., Collector Size 3" O.D., Port Shape: Same As Port, Ceramic Metallic Coating

Installation Notes
Factory style motor mounts must be used to ensure proper engine locations and header fit. Aftermarket solid and urethane mounts, worn or incorrect mounts will cause header fitment issues. If you have floor pan clearance issues on the pass side header, check your sub-frame mounts.

This header will not fit with close ratio steering box or rack conversions.

WARNING! 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 the Holley tech service at 1-866-464-6553 for additional information regarding ceramic-coated exhaust products.
