Exhaust System: Notes

The 2.3L exhaust system consists of:

• a one-piece catalytic converter manifold.
• an exhaust flexible pipe.
• an underbody catalytic converter.
• a production muffler and tailpipe assembly.
• isolators installed on the body and muffler hangers.

The 3.0L exhaust system consists of:

• a one-piece catalytic converter manifold(s) (LH on all vehicles, RH on front wheel drive [FWD] vehicles).
• an exhaust manifold mounted catalytic converter (RH on all wheel drive [AWD] vehicles).
• an exhaust flexible pipe.
• an underbody catalytic converter.
• a production muffler and tailpipe 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 tailpipe 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.
