Product Details

The Hooker 8527HKR exhaust manifolds are engineered specifically for Small Block Chevrolet engines with raised D-port cylinder heads. These high-performance manifolds deliver improved exhaust flow and durability over stock components while maintaining a clean, factory-style appearance.

Key Features:

  • Designed for raised D-port cylinder heads with compatibility for standard straight and Vortec straight plug head designs
  • Large 1-5/8" cross-sectional area with 2-1/2" outlets for enhanced exhaust flow and performance gains
  • Constructed from high silicon-molybdenum ductile iron for superior high-temperature strength, oxidation resistance, and crack prevention
  • Includes weld-on flanges for simplified custom downpipe installation
  • Complete hardware kit included with mounting bolts and gaskets for both inlet and outlet flanges
  • Available in natural cast iron finish or optional ceramic coatings (silver, black, or titanium)
  • Cleaner, smoother appearance than OEM manifolds while retaining factory-style fit

These manifolds provide an excellent balance of performance, durability, and aesthetics for street and mild performance Small Block Chevy applications. The ductile iron construction ensures long-lasting reliability under demanding exhaust temperatures, while the optimized port design maximizes exhaust scavenging efficiency.
