Audi A4 Catalytic ConverterThe harmful exhaust emitted from most vehicles can be minimized by a catalytic converter. When the Clean Air Act was implemented it became a requirement in 1975. As per the "Act", all vehicles must make sure that their gas emissions are reduced by seventy-five percent. Catalytic converters have been on every brand new car since 1975.

The converter employs “catalysts” like platinum, rhodium, and sometimes palladium. What makes the exhaust less harmful in your vehicle is how the gas reacts to certain chemicals. The converter is proven to be more efficient in keeping those noxious fumes away from atmosphere. It continues to be modified and improved in various ways.
