Overview

These Hooker BlackHeart cast iron exhaust manifolds have a 2.50 inch outlet, natural cast 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:

  • 2.5 inch outlet diameter offers improved flow for maximum performance from a cast iron exhaust manifold
  • Tight tuck design provides universal fit for most popular chassis and a clean traditional muscle car appearance
  • Intended for GM LS engine swap applications where durability, quiet operation, and leak-free sealing is desired
  • Plain as-cast finish for a factory appearance
  • Nickel plated steel mating flanges, MLS mating flange gaskets, and mating flange hardware included
  • Cast from Hi-Silicon-Moly Ductile Iron to provide durability and corrosion resistance
  • Perfect complement to Hooker engine swap mount plates and Holley engine swap oil pans

This product is engineered to facilitate the installation of a later model, emissions friendly engine into a vintage / classic vehicle. Federal guidelines indicate that an engine swap is allowable if one or more of the following conditions apply:

  • If there is a reasonable basis for knowing that emissions are not adversely affected as described in EPA Memo 1A
  • The resulting vehicle is identical (with regard to all emissions related parts, engine design parameters and engine calibrations) to a certified configuration of the same or newer model year as the vehicle chassis
  • The vehicle is a uncontrolled vehicle - Vehicles that were manufactured before emission control regulations took effect are called uncontrolled vehicles. Aftermarket parts regulations and anti-tampering laws do not apply to these vehicles
  • An EO legal engine swap kit is utilized (such as a GM EROD)
  • The vehicle is being used for Competition Use Only - Racing Use Only Vehicles are vehicles that are used exclusively for competition that are not registered and that may never be used on the street
