Description

Super Competition GM LS-1,Tube Size 1.625", Collector Size 2.5", Port Shape: Round

Part Number: 2313HKR

Universal SUPER COMPETITION headers are great for racing 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 and Benefits

• 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 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 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
• Includes all necessary hardware & gaskets for a simple installation.
• Hooker’s high style design is tuned for low & midrange performance

Vehicle owners who have installed a LS-1 or derivative engine and need maximum frame rail clearance with complete access to engine mounts and starter.
NOTE: For proper fit of these Hooker Headers, engine swap relocation mounts (12611HKR) should be used to ensure proper location of engine into chassis.
NOTE: Hooker recommends the use of multi-angle spark plug wires for this application (example - MSD-32819).
WARNING! 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 a cast-iron exhaust manifold or an old header to break in new engines to avoid coating damage.
