Any service on the exhaust system should be performed when the system is cool. At every interval of periodic maintenance service and when vehicle is raised for other service, check exhaust system as follows:  Check rubber mountings for damage, deterioration or out of position.  Keep sufficient clearance between exhaust system component and underbody.  Check exhaust system for leakage, loose connection, dent & damage. If bolts or nuts are loosened, tighten them to the specified torque.  Check nearby body areas for damage, missing or mis-positioned part, open seam, hole, loose connection or any other defect which could permit exhaust fumes to seep into vehicle.

In addition to this it is recommended to run the vehicle at high speeds (80 to 100 kmph) for few km as this will help to flush the carbon soot deposits from exhaust system and closed coupled catalytic converter. High speed running of the vehicle may be done periodically to avoid chocking of Closed Coupled Catalytic Converter.
