Check exhaust pipes, muffler and mounting for improper attachment, leaks, cracks, damage or deterioration.
If anything is found, repair or replace damaged parts.
Removal and InstallationEBS00M3Y
Exhaust System
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. The system will be hot just after the
engine stops.
Be careful not to cut your hand on the heat insulator edge.
