NOTE: Do not use oil or grease-based lubricants on the isolators. These lubricants may cause deterioration of the rubber. This can lead to separation of the isolator from the exhaust hanger bracket during vehicle operation.

NOTE: The exhaust Y-pipe dual catalytic converter is a 2-piece assembly. The RH and LH converters can be serviced separately as needed.

With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING & LIFTING .
