Exhaust System: Service and Repair

Components

CAUTION:
^ Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat resistance, corrosion resistance, and shape.
^ Perform the operation with the exhaust system fully cooled down because the system will be hot just after engine stops.
^ Be careful not to cut your hand on the heat insulator edge.








Removal and Installation
REMOVAL
^ Disconnect each joint and mounting using power tool.
^ When removing main muffler, remove main muffler mounting bracket bolts.
^ Remove exhaust mounting bracket as follows:

1. Remove engine rear undercover.
2. Remove front cross bar.
3. Remove exhaust mounting bracket.

INSTALLATION
Note the following, and install in the reverse order of removal.





^ Tighten main muffler mounting bracket bolts in numerical order as shown in the figure.

CAUTION:
^ Always replace exhaust tube gaskets with new ones when reassembling.
^ If heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the heat insulator, remove them.
^ When installing heat insulator avoid large gaps or interference between heat insulator and each exhaust pipe.
^ Remove deposits from the sealing surface of each connection. Connect them securely to avoid gases leakage.
^ Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehicle side. Check each part for unusual interference, and then tighten them to the specified torque.
^ When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/left directions.

INSPECTION AFTER INSTALLATION
^ Make sure clearance between tail tube and bumper is even.
^ With engine running, check exhaust tube joints for gas leakage and unusual noises.
^ Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue stress. Improper installation could result in excessive noise and vibration.
