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.

  • Tuned-length primary tubes for maximum exhaust scavenging and velocity

Who is Hooker Headers?

Hooker Headers is a company founded by Gary Hooker in 1962. It started when he decided to design a header for his 409 Chevrolet. Soon after, he realized a demand for headers in his area and decided to produce them commercially. Starting with a few employees in a building in South Ontario, CA, Hooker Headers was born.

Simple Yet Effective Design

The company’s philosophy is simple, to produce a header design that would make real and usable power by balancing the exhaust and intake pressure waves. It allows the engine to expel the burnt gas and draw in air for a better fuel and air mixture. This philosophy is evident to all of their products, making them one of the most sought-after brands.

Racing Heritage

During the 1960s and 1970s, Hooker Headers dominated the drag racing scene as almost all of the NHRA Pro Stock cars are using Hooker Headers. It is also used by legendary racers Bill “Grumpy” Jenkins, Sox & Martin, and Bob Glidden and was a regular during their campaigns. Up to this day, Hooker Headers holds the claim of the winningest header in drag racing history.
