[More Info]
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.
Features:
  • Tuned Length Tubes For Street Performance
  • Long Transition Collector For Decreased Back Pressure
  • All Hardware Included
  • Mandrel Bent Tubing For Smooth Exhaust Flow
  • Machined Flange Provides Finest Fit
  • Best Industry Welds For Durable Design
Holley Performance Emission Code 4: This part is legal for sale or use on Racing Use Only Vehicles. The following vehicles are considered Racing Use Only Vehicles: Racing Use Only Vehicles are vehicles that are used exclusively for competition that are not registered and that may never be used on the street. WARNING: It is against the law to install this part on an Emissions Controlled Vehicle
Installation Notes:
Will not fit with angle plug heads or raised port heads. Installation requires air conditioning bracket 10925HKR left side or 10926HKR right side. On 1979 and later vehicles with short compressors, use stock bracket. 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.
