Exhaust System
WARNING: This page is about a different car, the 2009 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
When repairing exhaust system or removing exhaust components, disconnect all heated oxygen sensors (HO2S) at the wiring connectors to prevent damage to the HO2S and wiring harness. Refer to ELECTRONIC ENGINE CONTROLS
article for location of the heated oxygen sensors.
CAUTION:
Do not use oil or grease-based lubricants on the isolators. They may case deterioration of the rubber.
CAUTION:
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:
- contains a one-piece catalytic converter assembly.
- has one muffler assembly (4.0L).
- has a LH muffler assembly and a RH muffler assembly (4.6L and 5.4L).
- has muffler brackets with isolators at the front and rear of the muffler, bolted to the body.
- has 2 upstream heated oxygen sensors (HO2S) mounted to the catalytic converters (4.0L).
- has one upstream HO2S mounted to the LH exhaust manifold and one mounted to the RH catalytic converter (4.6L and 5.4L).
- production muffler and tailpipe assembly is a one-piece design exhaust system.
