[More Info]
Street Rod and Universal Super Competition Headers are great for custom car, truck, or street rod where a specific fit tuned Super Competition header is not available. They work great for those tight–fit installations where frame rails are close to the engine block. Stock motor mounts can be used. Because the collector exits parallel with the oil pan rail, maximum ground clearance is allowed. These headers come complete with gaskets, header bolts and collector reducers. These headers come available in chrome, high heat resistant black paint or Hookers metallic ceramic thermal barrier coating.
Features:
  • Tuned Length Tubes For Max Exhaust Scavenging/Velocity
  • Great For Tight-Fit Installation
  • Designed For Optimal Performance w/Best Welds
  • Mandrel Bent Tubing For Smooth Exhaust Flow
  • Machined Flange Provides Finest Fit
  • Includes All Hardware For Easy Installation
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:
These Headers can not be used with factory side engine mounts. Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. Ceramic coated headers require several heat cycles to fully cure before they will withstand extreme heat. Hooker recommends using cast iron exhaust manifolds or old headers to break in new engines to avoid coating damage. Please call Hooker tech service at 270-781-9741 for additional information regarding ceramic coated exhaust products.
