Universal SUPER COMPETITION headers are great for racing applications 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:

  • Includes all necessary hardware & gaskets for a simple installation.
  • Hooker’s high style design is tuned for low & midrange performance
  • Strong torque multiplication in an engine's operation range is from idle (800 RPM) to around 3,500 RPM
  • 1 5/8” Mandrel-bent, tuned-length primaries for decreased backpressure and increased exhaust velocity improving HP, torque, & throttle response
  • 2.5” Collector at 3-bolt flange for easy exhaust installation
  • 3/8” thick machined head flanges for perfect sealing surface
  • Lightweight 18 gauge mild steel tubing for strength and reliability
  • Tight-tuck tube design for fit with narrow hot rod frames
  • Collector exit is parallel with oil pan for maximum ground clearance
  • Collectors are positioned for maximum starter and engine mount clearance
  • Industry’s best welds for durability
