Header SBC Modified 1-5/8in 3in Col

The Header SBC Modified 1-5/8in 3in Col from Schoenfeld is a high-performance exhaust header specifically designed for small-block Chevrolet (SBC) engines that are undergoing significant modifications. This product is ideal for builders who seek enhanced scavenging efficiency and increased horsepower output while ensuring reliability. Whether you're constructing a street machine, a weekend warrior, or a track-focused engine, this header is engineered to meet your performance needs.

With a primary tube diameter of 1-5/8 inches, this header optimizes scavenging velocity across a broad RPM range, effectively preventing backpressure that can diminish mid-range torque and peak horsepower. The 3-inch collector is designed to facilitate smooth exhaust flow, reducing turbulence and heat loss as gases transition into the downstream piping system. Schoenfeld's modified design also addresses common engine bay clearance issues while maintaining optimal header tube geometry and bend radii.

This header is particularly beneficial for modified SBC applications, especially those utilizing aftermarket cylinder heads, cam profiles, and induction systems that aim for measurable power gains. Serious street and strip builders trust Schoenfeld's reputation for precision tube work and construction quality. The compact design allows for installation in tight spaces where stock or universal headers may not fit.
