INSTALLATION
Note the following items, and install in the reverse order of removal.
• Temporarily tighten bolts and nuts when installing exhaust pipe assembly. Tighten them to the specified
torque when connecting the vehicle rear to the vehicle front.
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.
• 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
• Check clearance between tail tube and rear 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.
