Exhaust Manifold Set GM LS w/SBC Exit

The HOOKER Exhaust Manifold Set GM LS with Small Block Chevy Exit is a cast iron exhaust manifold pair engineered for engines running LS-series heads with small block Chevy exhaust exit configuration. These manifolds deliver proven durability and thermal management in high-performance marine and automotive applications where reliable exhaust scavenging is critical to engine efficiency and longevity.

Cast iron construction provides superior heat retention and durability compared to thin-wall alternatives, particularly important in marine environments where sustained operation and thermal cycling demand robust materials. The black ceramic coating protects against corrosion and oxidation while resisting high exhaust temperatures, extending manifold life in salt air and variable humidity conditions. The 2.5-inch outlet diameter accommodates mid-range exhaust flow without excessive backpressure, making this set compatible with naturally aspirated and moderately boosted engines. At 27.84 lbs, the pair represents proper mass and wall thickness necessary for long-term reliability under continuous duty.

This manifold set suits builders transitioning LS powerplants into classic vehicles, sport boats, and performance platforms where modern LS efficiency meets small block Chevy spacing. The configuration resolves the common challenge of fitting newer LS engines into legacy engine bays without custom fabrication. Buyers restoring or upgrading marine engines, street rods, and vintage muscle platforms will find these manifolds provide the dimensional compatibility and thermal performance required for reliable long-term operation without modification to existing exhaust systems designed for small block geometry.
