Exhaust car catalytic converters are essential components that help to reduce harmful emissions from vehicles. They are installed in the exhaust system and work by converting toxic gases such as carbon monoxide, nitrogen oxides, and hydrocarbons into less harmful substances such as carbon dioxide, nitrogen, and water vapour. This process helps to reduce air pollution and improve the quality of air we breathe. Catalytic converters are available for a wide range of vehicles and are a recommended addition to any car.
