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, 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. |
Description_MKT | 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. |
