Description

Part #: 8501-1HKR

These Hooker BlackHeart cast iron exhaust manifolds have a 2.25-inch outlet, silver ceramic finish, and are designed to hug close to the engine block so they fit into a wide variety of replacement and engine-swap applications. Their contoured design aims the exhaust directly toward the exit port for improved flow. Being cast iron means they will provide years of leak-free performance with less under-hood noise than traditional headers. Plus, their shorty design means you can route exhaust tubing close to your frame/floor pan for maximum ground clearance.

Features:

  • Intended for GM LS engine swap applications where durability, quiet operation, and leak-free sealing is desired
  • Tight Tuck Design Provides Universal Fit
  • Silver ceramic coating for reduced engine compartment temps and improved corrosion resistance
  • Free-Flowing For Good Performance
  • Nickel plated steel mating flanges included (mating flange fasteners are not included)
  • Catalytic Converter Efficiency
  • 2.25 inch outlet diameter offers improved flow for maximum performance from a cast iron exhaust manifold
  • Hi-Silicon-Moly Ductile For Durability
  • 2 bolt exit flange configuration matches the E-rod exhaust manifolds for a factory like fitment. This allows the use of factory gaskets and fasteners if desired
  • Corrosion Resistant
  • Cast from Hi-Silicon-Moly Ductile Iron to provide durability and corrosion resistance
  • 2 Bolt Exit Flange Configuration
  • Tight tuck design provides universal fit for most popular chassis and a clean traditional muscle car appearance
  • Perfect Complement To Engine Swap Mount Plates
