Average quote for a catalytic converter replacement
The catalytic converter is part of the exhaust system that looks similar to a silencer but smaller. It is often located close to the exhaust manifold and the engine, allowing it to heat up quickly. It changes harmful exhaust gases, like nitric oxide and carbon monoxide, into less toxic substances, like water vapour and carbon dioxide, via chemical reactions.
Several things can go wrong with a catalytic converter, requiring a replacement. These include overheating, physical damage (from driving over a curb, for example), contamination from leaking oil, coolant or fuel, and age. Unfortunately, catalytic converter theft is common due to the precious metals in them; without one, your car will fail its MOT.

Signs of a faulty catalytic converter
Catalytic converters are designed to last a long time - around ten years or 100,000 miles - but sometimes wear out early. When this happens, your car will likely feel sluggish and struggle to accelerate. It’s common to experience a rotten egg smell from the exhaust and extreme heat beneath the vehicle. In some models, the check engine light may appear on the dashboard.
Make sure you have your car checked by a mechanic as soon as you notice any of these symptoms to avoid engine damage due to heat.
