The three way catalytic converter is an emission control device added to the exhaust system to reduce pollutants in the exhaust gas stream and requires the use of unleaded fuel only.

The three way catalytic converter coating contains platinum and rhodium which lowers the levels of Oxides Of Nitrogen (NOX) as well as Hydrocarbons (HC) and Carbon Monoxide (CO).

Periodic maintenance of the exhaust system is not required. If the vehicle is raised for other service, it is advisable to check the condition of the complete exhaust system.
