Product Details

The Hooker 8527-3HKR exhaust manifolds are specifically engineered for Small Block Chevrolet engines with raised D-port cylinder heads. These performance-oriented manifolds deliver improved exhaust flow while maintaining a clean, factory-style appearance that's perfect for street and performance applications.

Key Features:

  • Designed specifically for raised D-port heads with accommodation for standard straight and Vortec straight plug head designs
  • Larger 1-5/8" cross-sectional area with 2-1/2" outlets for enhanced exhaust flow and increased horsepower
  • Constructed from high silicon-molybdenum ductile iron for superior high-temperature strength and resistance to oxidation and cracking
  • Includes weld-on flanges for simplified custom downpipe installation
  • Complete hardware kit included with mounting bolts and gaskets for inlet and outlet flanges
  • Available in multiple finishes: natural cast iron or ceramic coated options in silver, black, and titanium
  • Cleaner, smoother appearance compared to original equipment manifolds while retaining OE-style fitment

These manifolds provide an excellent balance of performance gains and street-friendly sound levels, making them ideal for enthusiasts who want improved flow without the hassle of full exhaust headers. Custom downpipes are required for installation.
