What is a Catalytic Converter or Cat?
The Catalytic Converter (commonly known as a Cat) is a device that helps to reduce the harmful emissions from your vehicle's engine.
How does it work?
The Cat works by filtering the exhaust gases through an internal honeycomb section known as a Monolith. The Monolith is either ceramic or metal and is coated with precious metals such as Platinum, Palladium and Rhodium. Using a combination of heat and precious metals the Catalytic Converter promotes a chemical reaction that reduces the harmful emissions of hydrocarbons, carbon monoxide and nitrogen oxides and converts them into water vapour and less harmful gases.
Do I Need a Type Approved Cat?
If your car is X registration or older and therefore first registered before 1st March 2001 you DO NOT need to buy a Type Approved catalytic converter.
