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\" 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.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTuned-length primary tubes for maximum exhaust scavenging and velocity\u003c\/li\u003e\n\u003cli\u003eMandrel-bent tubing for smooth exhaust flow\u003c\/li\u003e\n\u003cli\u003eSturdy 16 gauge tubing\u003c\/li\u003e\n\u003cli\u003eLong transition collector for decreased back pressure\u003c\/li\u003e\n\u003cli\u003e5\/16\" machined flanges for a perfect seal\u003c\/li\u003e\n\u003cli\u003eIndustry's best welds for durability\u003c\/li\u003e\n\u003cli\u003eDesigned for strong performance\u003c\/li\u003e\n\u003cli\u003eAll necessary hardware included for a complete installation\u003c\/li\u003e\n\u003cli\u003eWorks with factory power steering, power brakes and air conditioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eLong Tube Headers for 1969-1974 Blazer\/Jimmy\/Yukon\/Tahoe 2DR.
