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.
