Overview 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% better. That commitment to excellence has made Hooker Headers the winningest header manufacturer in automotive drag racing history. Features Tuned-length primary tubes for maximum exhaust scavenging and velocity Mandrel-bent tubing for smooth exhaust flow Light weight & sturdy 18 gauge tubing Long transition collector for decreased back pressure 5/16" machined flanges for a perfect seal Industry's best welds for durability Designed for optimal performance All necessary hardware included for a complete installation Applications Year Make Model Engine Fitment Notes 1967-1969 Dodge Dart 6.3L V8 383 CID See Below! 1967-1969 Plymouth Barracuda 6.3L V8 383 CID See Below! Fitment Notes Will NOT fit motors equipped with a Air Injection Pump without modification. Hooker headers for MOPAR 383-440 engines will bolt on the popular aftermarket B-S heads. However, because the exhaust port centerline on these heads is 5/8” higher and 3/8” out from the engine centerline compared to stock heads, some header modifications will be required for installation. Custom header applications will be required to fit the B-1 heads because of angled spark plug location. Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. Hooker recommends using cast iron exhaust manifolds or old headers during your engine break-in period to avoid damaging your coated damage. The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Hooker does not recommend the use of header wraps as this will void the warranty.
