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.

Strong torque multiplication in an engine's operation range is from idle (800 RPM) to around 3,500 RPM
