Exhaust System: Notes
WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The 2.5L exhaust system consists of:
- a one-piece catalytic converter manifold (hybrid only).
- an exhaust manifold (except hybrid).
- an exhaust flexible pipe.
- an underbody catalytic converter.
- a Catalyst Monitor Sensor (CMS) mounted to the underbody catalytic converter.
- a production muffler and tail pipe assembly.
- isolators installed on the body and muffler hangers.
The 3.0L exhaust system consists of:
- a one-piece catalytic converter manifold.
- a RH exhaust manifold-mounted catalytic converter.
- an exhaust flexible pipe.
- an underbody catalytic converter.
- a production muffler and tail pipe assembly.
- isolators installed on the body and muffler hangers.
The 3.5L exhaust system consists of:
- two exhaust manifold-mounted catalytic converters.
- an exhaust Y-pipe.
- a resonator and flex assembly.
- a production muffler and tail pipe assembly.
- isolators installed on the body and muffler hangers.
The exhaust system provides an exit for exhaust gases and reduces engine noise by passing exhaust gases through the catalytic converters, a muffler assembly and resonator. Rubber exhaust hanger isolators attach the exhaust system to the hangers welded on the body.
