All You Need to Know About Buying Car Exhaust Catalytic Converters
Frequently Asked Questions (FAQs)
A catalytic converter is a unit installed in the front part of a vehicle’s exhaust system, near the engine, to reduce the emission of pollutants such as carbon monoxide, nitrogen oxides, and hydrocarbons.
Without catalytic converters, vehicles would release these harmful gases, which are a significant source of ground-level ozone and smog, causing damage to the environment.
Catalytic converters contain rare earth metals like platinum, palladium, or rhodium, which are the primary targets for theft due to their high monetary value, as stated by the National Insurance Crime Bureau and the PBS NewsHour.
A vehicle will be equipped with a catalytic converter for each exhaust pipe—consequently, while most automobiles will only require one, dual exhaust vehicles will necessitate the installation of two. Catalytic converters became the industry standard after 1975, and the majority of dual exhaust vehicles are equipped with V8 engines.
