Ford Mustang (1999-2004) Service Manual: Exhaust System (Description and Operation)
WARNING: The normal operating temperature of the exhaust system is very high. Never attempt to repair any part of the system until it has cooled. Be especially careful when working around the three way catalytic converter. The temperature of the three way catalytic converter rises to a high level after only a few minutes of engine operation.
CAUTION: When repairing exhaust system or removing exhaust components, disconnect all heated oxygen sensors (HO2S) at the wiring connectors to prevent damage to the heated oxygen sensors and wiring harness. For additional information, refer to Section for location of the heated oxygen sensors.
The exhaust system:
- contains dual three-way catalytic converters.
- has a crossover pipe downstream of the three way catalytic converters (4.6L).
- has two upstream heated oxygen sensors mounted before the three-way catalytic converters.
- the production muffler and tailpipe assembly is a one-piece design exhaust system.
