Exhaust System: Notes

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.
