Part Details Vehicle Fitment Reviews
Hooker's new cast iron small-block Chevy 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. Offered for both rectangular or raised D-port heads, these manifolds fit many popular GM applications including standard straight, Vortec straight and angled plug head designs. Finishes include natural, silver, black, and Natural Finish. Gaskets and hardware are included, along with weld-on flanges to aid in downpipe installation
