Exhaust System

NOTICE: When repairing exhaust system or removing exhaust components, disconnect all Heated Oxygen Sensor (HO2S) and all Catalyst Monitor Sensor (CMS) at the wiring connectors to prevent damage to the HO2S and CMS wiring harnesses. Refer to Electronic Engine Controls for location of the HO2S and CMS. [1][2]Exploded Views

NOTICE: Oil or grease-based lubricants on the isolators may cause the exhaust hanger isolator to separate from the exhaust hanger bracket during vehicle operation.

NOTE: Exhaust fasteners are of a torque-prevailing design. Use only new fasteners with the same part number as the original. Torque values must be used as specified during reassembly to make sure of correct retention of exhaust components.

The exhaust system:
- has an exhaust Y-pipe dual catalytic converter that is a 2-piece assembly. The RH and LH converters can be serviced separately as needed.
- has 2 upstream Heated Oxygen Sensor (HO2S) mounted before the catalytic converters.
- has 2 Catalyst Monitor Sensor (CMS) mounted on catalytic converters.
- has an intermediate pipe.
- has muffler brackets with isolators at the front and rear of the muffler, bolted to the body.
- production muffler and tail pipe assembly is a one-piece design.
