Hooker's new cast iron exhaust manifolds offer an increase in performance and visual appearance over stock-style manifolds. Their compact design fit into a wide variety of replacement and engine swap applications. This means you get the traditional look and easy fitment of a stock style exhaust manifold but now with a smoother, cleaner appearance, plus more modern features. These manifolds are cast out of high silicon-molybdenum ductile iron for high temperature strength and better resistance to oxidation and cracking. Internally these manifolds have a larger than stock 1-5/8 inch cross-sectional area and 2-1/2 inch outlets for better air flow and improved performance. These are for raised D-port heads, rectangular versions are also available. These manifolds are compatible with many popular GM applications including standard straight, Vortec straight and angled plug head designs. These are in a natural cast-iron finish, but silver, black, and titanium ceramic coated versions are also available. Gaskets and hardware are included, along with weld-on flanges to aid in downpipe installation.

These cast exhaust manifolds have been designed to fit into a wide variety of replacement and engine-swap applications, with final outlet connections to be fabricated by the installer. The manifolds will not directly bolt onto factory downpipes.

Does not fit 1967-1969 Camaro/Firebird.
