Why do CAT s get stolen?

No, not those cats. A CATin car terms is a catalytic converter – a clever device that is found in the exhaust system of modern cars. A CATconverts the toxic gases and pollutants in exhaust gases into safer, less harmful emissions. To do this it uses a catalyst (hence the name) that causes a chemical reaction to change the make-up of the toxic gases, converting them to less harmful compounds. Most CATs are 3-way CATs , which means that they convert three different pollutants. They reduce nitrogen oxides to nitrogen, and they cause the oxidation of carbon, hydrocarbons and carbon monoxide to carbon dioxide.

Cats need very high temperatures, over 400°C, to operate efficiently, so are placed close to the engine.

So why do people steal them? Because the chemical reactions that take place in the dark inner workings of a cat are caused by precious metals including platinum, palladium and rhodium, as well as cerium, copper, iron, manganese and nickel. Cats are also quite easy to steal, situated as they are on the underneath of the vehicle. Some cats are just bolted onto the exhaust, so can be even easier to (quietly) steal – others can be removed with cordless power tools or even manual pipe cutters.

A popular misconception is that only petrol cars have cats: not true – diesel vehicles also have cats, usually called diesel oxidation catalysts (DOC). They work in conjunction with exhaust gas recirculation and a diesel particulate filter (DPF) to cleanse the emissions.

Your Toyota will have sensors on the cat and DPF, notifying you if there is an issue. That is unlikely though, as these components self-clean at high temperatures.

It is illegal to operate a vehicle without a factory-fitted cat, because they reduce emissions so effectively. They do, however, reduce the engines power output by a few percent, so some drivers take the illegal risk and remove cats for gains in power and fuel economy, especially on older vehicles.

Wow: Amazingly, catalytic converters were first designed at the end of the 19th century, in France!
