The Hooker Super Competition Long Tube Header 2457-1HKR is engineered for Chevy Big Block engines, enhancing both the performance and sound of your vehicle. With a focus on optimal exhaust scavenging and velocity, this header utilizes 2” x 27” tuned-length tubes and a 3.5” long transition anti-back pressure collector for maximized performance. Finished with a metallic ceramic coating, it not only withstands high temperatures but also adds a sleek look under your hood. The durable 16-gauge mild steel construction and mandrel-bent tubing ensure consistent tube diameter and superb exhaust flow, contributing to increased horsepower and torque for your Chevrolet. Ideal for both street and strip applications, it maintains header integrity with 5/16" machined flanges that promise a perfect seal on the exhaust ports. Supplied with all necessary hardware, installation is straightforward, although professional fitting is recommended for optimal results. If your vehicle exhibits symptoms like reduced engine power, increased backpressure, or a raspy exhaust tone, upgrading to the Hooker Header could be your solution. Pair this must-have component with high-quality gaskets and performance catalytic converters for a comprehensive exhaust upgrade that truly transforms your driving experience.
