Exhaust Pipe Replacement Intermediate

1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
2. Remove the exhaust tailpipe. Refer to Tail Pipe Replacement .



3. Loosen the clamps from the front and rear of the intermediate exhaust pipe.
4. Remove the exhaust system from the hangers.
5. Remove the exhaust pipe from the vehicle.

1. Install the exhaust pipe on the vehicle.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.




2. Install the clamps at the front and rear of the exhaust pipe.

Tighten
Tighten the clamps to 68 N·m (50 lb ft).

3. Install the exhaust tailpipe. Refer to Tail Pipe Replacement .
4. Lower the vehicle.

3. Disconnect the oxygen sensor connectors.
4. Remove the oxygen sensors from the front pipe. Refer to Heated Oxygen Sensor Replacement in Engine Controls.
5. Remove the exhaust pipe nuts and seals from the exhaust manifolds.
6. Remove the exhaust pipe from the vehicle.

1. Install the exhaust pipe and new seals to the exhaust manifolds and the exhaust pipe flange and new gasket to the catalytic converter.



2. Install the exhaust pipe to manifold retaining nuts.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
