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.

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._x000D_ _x000D_ NOTE: For proper fit of these Hooker Headers, engine swap relocation mounts (12611HKR) should be used to ensure proper location of engine into chassis._x000D_ _x000D_ NOTE: Hooker recommends the use of multi-angle spark plug wires for this application (example - MSD-32819)._x000D_ _x000D_ 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.
