Hooker Super Competition Block Hugger headers are a great choice for your custom car, truck, or rod. Ideal for applications where the frame rails are close to the engine block. These headers feature a tucked-in tube design that's perfect for those tight-fit installations! Mandrel-bent, tuned-length primaries decrease backpressure and increase exhaust velocity, improving horsepower, torque, and throttle response. Their collectors are positioned for maximum starter and engine mount clearance; and exit parallel with the oil pan rail to allow for maximum ground clearance. Hooker Super Competition Block Hugger headers come complete with the gaskets, header bolts and collector reducers needed for a successful installation.
