Tech Resources

When connecting mid length headers and cast iron manifolds to our full exhaust kits, an adapter pipe is required to fill that gap between the end of the headers or 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
