SBC Side Mount Headers 304 S/S - 63-82 Vette

The SBC Side Mount Headers 304 S/S - 63-82 Vette by Doug's Headers represent the gold standard for classic Corvette exhaust manifold upgrades. Built for the serious enthusiast who refuses to compromise on fit, finish, or flow, these side-mount headers transform a stock small-block Chevy into a responsive, free-breathing engine. Whether you're restoring a first-generation C2 or maximizing performance on a C3, these headers eliminate the restrictive factory cast-iron manifolds that plague vintage Corvettes and unlock hidden horsepower and torque across the RPM band.

Manufactured from 304 stainless steel, these headers resist rust and corrosion far better than mild-steel alternatives, crucial for vehicles exposed to road salt or stored seasonally. The side-mount design routes exhaust away from the engine bay perimeter, reducing underhood heat and improving cooling efficiency while maintaining authentic vintage aesthetics that stock headers cannot match. Doug's Headers engineers each tube diameter and length to optimize scavenging—the process where exiting exhaust gases create a low-pressure zone that pulls fresh mixture from the cylinders—resulting in measurable gains in volumetric efficiency, especially at higher RPMs.

These headers bolt directly to 1963–1982 Corvettes with small-block Chevy engines, requiring minimal modification to existing exhaust systems and engine bay components. Installation typically demands removal of the starter and careful routing past transmission and chassis, making professional installation or solid mechanical aptitude essential. At 66 pounds, they add negligible weight while delivering noticeable improvements in throttle response, engine sound clarity, and fuel efficiency on stock or modified engines—making them an investment that pays dividends in both performance and driving satisfaction.
