    LS Exhaust Manifold

    Note: Fitment issues may occur with models equipped with air conditioning. Modification to brackets may be required. Not compatible with 2004-2006 GTO starters/bellhousings.

    Specifications:

    Manufacturer's Part Number:
    30140

    JEGS Cast Iron Exhaust Manifolds are designed to fit close to the engine block and provide years of leak free performance. The tucked-in design directs exhaust to the exit port for improved flow and allows you to route exhaust tubing close to your frame/floor pan for maximum ground clearance. These manifolds are intended for most GM LS engine swaps where durability, quiet operation, and a leak-free seal is desired.

    Features:

    • Recommended for engines up to 500 horsepower
    • Tight design provides universal fit for most popular chassis
    • Free-flowing for catalytic converter efficiency
    • Cast Iron to provide endurance and corrosion resistance
    • 2-bolt exit flange
    • Raw or ceramic finish
    • Can be used with OE gaskets & fasteners

    I don't see flange gaskets in the pictured details. What type of gasket does this 2-bolt style flange use? What part number, and do you offer it? Thanks, Scott
