Checking Exhaust SystemBBS005AK
Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage or deterioration.

If necessary, repair or replace damaged parts.
Removal and InstallationBBS005AL
WARNING:
Be careful not to cut your hand on heat insulator edge.
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.
