Exhaust Manifold JRspec for Chevrolet LS1 LS2 LS3 4.8 5.3 6.0

A compact exhaust manifold designed for LS engine swaps, constructed from high-strength cast iron. Its tight-fit design positions the manifold close to the engine block, making it suitable for projects with limited space. Profiled runners direct exhaust gases efficiently to the outlet port, enhancing flow and reducing under-hood temperatures compared to tubular headers.

Includes exhaust flanges and gaskets.
