[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 percent better. That commitment to excellence has made Hooker Headers the winningest header manufacturer in automotice drag racing history.

  • Designed For Optimal Performance
  • Long Transition Collector For Decreased Back Pressure
  • Mandrel Bent Tubing For Smooth Exhaust Flow
  • Machined Flange Provides Finest Fit
  • Best Weld For Durability

Holley Performance Emission Code 4: This part is legal for sale or use on Racing Use Only Vehicles. The following vehicles are considered Racing Use Only Vehicles: Racing Use Only Vehicles are vehicles that are used exclusively for competition that are not registered and that may never be used on the street. WARNING: It is against the law to install this part on an Emissions Controlled Vehicle
Installation Notes:
Does not work with raised port heads. 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. Factory style big block frame stands and motor mounts must be used to ensure proper engine locations and header fit. Many aftermarket mount brands relocate motor location which causes the headers to hit certain components.
