OMC 460 Ford Replacement Cast Aluminum Exhaust System - 4" or 3.5"

These New Premium Direct bolt 460 Ford manifolds are the ultimate solution for the person looking for a direct bolt on style manifold system for early OMC style applications. Direct bolt on means no leaking adapters or odd hardware to fuss with. Hardin Marine has produced Performance Ford center rise exhaust systems for decades and now is adapting the performance style manifolds and riser to replace OEM OMC Systems . Two systems are offered with one using the 3.5" Y-Pipe hose connection the other a 4" Y-pipe connection.

Hardin adapted the same technology used to develop the powerful manifold systems found on Mercury Racing’s engines to the Ford 460. Individual separated runner port designs provide for improved exhaust efficiency while reducing exhaust back pressure.These manifolds are cast from pure T356 aluminum and then heat treated Included features such as hard anodizing for corrosion resistance and a gloss powder coated for a stunning appearance. Manifolds feature individual port water inlets for balanced even water flow thru the manifold. These exhaust systems require some customer supplied exhaust measurements. Allow 5-6 week lead times to build tailpipesl. (Not for use on Cobrajet heads)
