Street Rod/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: This is also evident during kickdown passing from 2nd to 3rd gear or whenaccelerating part throttle on to a freeway on ramp 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 exhaustinstallation 3/8� thick machined head flanges for perfectsealing surface Lightweight 18 gauge mild steel tubing forstrength and reliability Tight-tuck tube design for fit with narrow street 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 Includes all necessary hardware & gaskets for a simple installation. Strong torque multiplication in an engine''s street operation range is from idle (800 RPM) to around 3,500 RPM Hooker’s high style design is tuned for low & midrange street performance
