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.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAll necessary hardware included for a complete installation\u003c\/li\u003e\n\u003cli\u003eTuned Length Tubes For Max Exhaust Scavenging\/Velocity\u003c\/li\u003e\n\u003cli\u003edesigned for easy, trouble-free fit\u003c\/li\u003e\n\u003cli\u003eDesigned For Optimal Performance\u003c\/li\u003e\n\u003cli\u003eIndustry's best welds for durability\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\u003eMandrel Bent Tubing For Smooth Exhaust Flow\u003c\/li\u003e\n\u003cli\u003eLong transition collector for decreased back pressure\u003c\/li\u003e\n\u003cli\u003eMachined Flange Provides Finest Fit\u003c\/li\u003e\n\u003cli\u003eLight weight \u0026amp; sturdy 16 gauge tubing\u003c\/li\u003e\n\u003cli\u003eBest Weld For Durability\u003c\/li\u003e\n\u003cli\u003eMandrel-bent tubing for smooth exhaust flow\u003c\/li\u003e\n\u003cli\u003eAll Hardware Included\u003c\/li\u003e\n\u003cli\u003eTuned-length primary tubes for better performance\u003c\/li\u003e\n\u003cli\u003eWorks with power steering, power brakes and air conditioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eLong Tube Headers for 1955-1974 Corvette with 265-400ci V8 engines, Primary Tube Size 1.625\" x 24\" O.D., Collector Size 3\" O.D., Collector Length 8\", Header Port Shape: Same As Engine Port\u003c\/p\u003e\u003cp\u003eThis product may expose you to chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.\u003c\/p\u003e","brand":"Hooker","offers":[{"title":"Default Title","offer_id":51827911524664,"sku":"H00I 2456HKR","price":357.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/578155858.webp?v=1778806489","url":"https:\/\/store.motormia.co\/products\/exhaust-header-171","provider":"MOTORMIA","version":"1.0","type":"link"}
