[More Info]
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
  • All necessary hardware included for a complete installation
  • Designed for optimal performance
  • Industry’s best welds for durability
  • 5/16” machined flanges for a perfect seal
  • Long transition collector for decreased back pressure
  • Light weight & sturdy 18 gauge tubing
  • Mandrel-bent tubing for smooth exhaust flow
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. Please call Hooker tech service at 270-781-9741 for additional information regarding ceramic coated exhaust products. 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. Hooker long tube headers do not come with header reducers.
