Hooker 2451-1HKR Super Competition Long Tube Header

With Hooker Super Competition the objective has always been to make the maximum horsepower and to put it at the optimum point in the power curve. It takes a lot of time and money to do the job right. We will sometimes spend up to 2 to 3 times more just to make the Super Competition header work only 5 to 10 percent better. That commitment to excellence has made Hooker Headers the winningest header manufacturer in automotice drag racing history.

Description_MKT	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 in. machined flanges. 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.
