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 gas 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.
