What is a Catalytic Converter?

Catalytic converters (or CATs) have been a legal requirement on all petrol cars since 1993. Catalytic converters stimulate chemical reactions that reduce harmful gasses emitted into the atmosphere. The catalytic converter is an integral part of a car’s emissions and exhaust system, its operating temperature is 350 - 400°C. There are many signs that a catalytic converter will need to be replaced, including engine performance and a distinctive (and unpleasant) odour.
