Product Details
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. 1967-1987 1/2, 3/4 & 1 Ton Truck (4WD) 1969-1991 Blazer-Jimmy/Yukon/Tahoe 2 DR. (4WD)
