Exhaust System: Notes

The 2.5L exhaust system consists of:

• an exhaust downpipe.
• an exhaust intermediate pipe.
• a Catalyst Monitor Sensor (CMS) mounted to the underbody catalytic converter.
• an underbody catalytic converter and muffler assembly that is a 1-piece design (OEM) and a 2-piece design for service.
• muffler brackets with isolators bolted to the body.
• a resonator tailpipe assembly.

The 3.0L exhaust system consists of:

• a 1-piece LH catalytic converter manifold.
• a RH exhaust manifold mounted catalytic converter.
• an exhaust Y-pipe.
• an underbody catalytic converter and muffler assembly that is a 1-piece design (OEM) and a 2-piece design for service.
• muffler brackets with isolators bolted to the body.
• a resonator tailpipe assembly.

The 2.5L hybrid exhaust system consists of:

• a 1-piece catalytic converter manifold.
• an intermediate pipe.
• an underbody catalytic converter and muffler assembly that is a 1-piece design (OEM) and a 2-piece design for service.
• muffler brackets with isolators bolted to the body.
• a resonator tailpipe assembly.

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 insulators attach the exhaust system to the mounting hooks.
