Exhaust Header Set - LS Swap GM F-Body 75-81

The Exhaust Header Set - LS Swap GM F-Body 75-81 from Doug's Headers is designed for enthusiasts looking to integrate modern LS powerplants into classic Chevrolet and Pontiac F-Body platforms. This header set addresses the challenge of fitting LS engine factory exhaust manifolds into the tight engine bay of second-generation F-Bodies without extensive modifications.

Constructed from high-temperature-rated steel tubing, the headers feature mandrel-bent primary tubes that maintain consistent diameter and wall thickness, which helps reduce turbulence and maximize exhaust gas velocity. The design aims to optimize exhaust scavenging, improving low-end torque and mid-range power delivery across the RPM range. This construction method also enhances durability compared to crush-bent alternatives.

Ideal for LS swap enthusiasts building weekend track cars, street machines, or restoration projects, this header set is compatible with GM F-Body models from 1975 to 1981. It is essential for builders to verify clearance and use quality fasteners during installation to ensure optimal performance and fit.
