Dorman - OE Solutions Exhaust Manifold with Integrated Catalytic Converter P/N:674-891
Dorman 674-066 exhaust manifold catalytic converter for the 2010-2012 Ford Fusion 4-cylinder 2.5L and other vehicles collects exhaust gas from the cylinders and treats it in a catalytic converter built into the same piece.
A ticking or hissing exhaust leak near the manifold, a rattle from inside the unit or a check engine light can mean the exhaust manifold catalytic converter is failing. Before you replace it, rule out a leaking gasket, a loose flange or a sensor fault with a shop test, since those can look similar from the driver's seat.
This part fits the 2010-2012 Ford Fusion 4-cylinder 2.5L, the 2011-2012 Lincoln MKZ 4-cylinder 2.5L and the 2010-2011 Mercury Milan 4-cylinder 2.5L, and each takes one. It is a direct replacement designed to fit and perform like the original equipment on these vehicles.
