Dust or water in the rear compartment may be an indication of a problem in one of these areas.

Periodic maintenance of the exhaust system is not required. If the vehicle is raised for other service, it is advisable to check the condition of the complete exhaust system.

On the single exhaust system the resonator and the exhaust pipe are serviced as a unit. The exhaust muffler and the tail pipe are serviced as a unit.

On the dual exhaust system, the left-hand exhaust muffler, the tail pipes, and the partial exhaust pipes are serviced as one unit. The right-hand exhaust muffler and the tail pipes are serviced as one unit. The resonator and the exhaust pipe are serviced as one unit.

Various types of hangers are used to support the exhaust systems. These include:

Two types of clamps are used for connecting exhaust system slip joints:

Coat the slip joints with exhaust system sealer before assembling.

When servicing a welded connection, clamp the new connection. When installing replacement parts, coat the slip joints with exhaust system sealer before assembling.

Service the three individual components of the single exhaust system as follows:

Service the four individual components of the dual exhaust system as follows:
