Overview

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.
