Long Tube Exhaust Headers

The Hedman 68280 long-tube exhaust headers are engineered for a precise fit on 1963-1982 Chevrolet Corvettes equipped with small-block Chevy 283-400ci engines and factory side pipes. Constructed from durable, uncoated mild steel, these headers feature 1-5/8 inch primary tubes that lead to a 3-inch collector, optimizing exhaust flow for improved performance. These headers are designed for chassis exit and boast a substantial 0.25-inch flange thickness for robust sealing. The full-length design aims to enhance exhaust scavenging and potentially increase horsepower and torque. While the black paint is applied for pre-installation protection, it is not high-temperature resistant and may require further treatment or coating depending on the desired finish and longevity. Installation may require factory side exhaust cut and welding. It is important to note that this part is not legal for sale or use in California on pollution-controlled motor vehicles.
