SBC EXH MANIFOLD 2.5 OUTLET, BLACK

These cast exhaust manifolds are designed for a wide variety of replacement and engine-swap applications for Small Block Chevy engines. They feature a black ceramic finish and are made from high silicon-molybdenum ductile iron for high temperature strength, oxidation resistance, and crack resistance. They have a larger 1 5/8" cross-sectional area and 2.5" outlets for improved airflow and performance compared to stock manifolds. They are designed for rectangular port heads and accommodate both standard straight and Vortec straight plug head designs. The manifolds include weld-on flanges for easier downpipe installation (custom downpipe required) and mounting hardware and gaskets for inlet and outlet flanges.
