Emissions

This product is engineered to facilitate the installation of a later model, emissions friendly engine into a vintage / classic vehicle.

See Emissions Details
When connecting cast iron manifolds to our full exhaust kits, an adapter pipe is required to fill that gap between the end of the manifolds and our Hooker exhaust systems (which are designed to work with long tube header systems). Hooker has created a full line of adapter tubes that fill the gap and include all hardware and gaskets for a clean and simple connection.

Features:

  • Designed to work with Cast Iron Manifold and PN 42505HKR 2.5" exhaust system with flanges designed for easy bolt up on either end. Made from stainless steel for long life. 2.5" diameter tubing used throughout.

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 the EPA Tampering Policy dated November 23rd, 2020
  • 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
