Description

The Crossover Header 1-3/4 GM LS is a purpose-built exhaust manifold designed for Gen III and Gen IV LS-platform engines, ideal for street, strip, and road-course applications. Manufactured by Schoenfeld, this header is engineered to enhance airflow for high-performance LS swaps, addressing the limitations of factory cast-iron manifolds.

Featuring 1-3/4-inch primary tubes, the crossover design merges both cylinder banks into a single outlet, promoting superior scavenging characteristics. The mandrel-bent steel tubing construction ensures smooth internal transitions, maximizing exhaust velocity and minimizing turbulence, which is crucial for performance applications.

Enthusiasts and performance shops will find the Crossover Header 1-3/4 GM LS beneficial for optimizing engine performance in various builds, including modern restomods and performance trucks. Its design simplifies intake manifold fitment in tight engine bays, making it a versatile choice for serious automotive projects.
