What does a catalytic converter do?

The catalytic converter is located under the car as part of the exhaust system. Because it sits under the car it will be exposed to all types of weather and road conditions thru its life span.

Catalytic converters are a part of the exhaust system, the job of the converter is to reduce the toxic gases and pollutants from engine exhaust.  The converter’s catalyst (honeycomb) is made up of palladium, rhodium, and palladium.

Typically, because of new regulations, the need for efficient and good catalytic converters are more of a focus for cat manufacturers.

*Keep In Mind* A catalytic converter oftentimes gets mistaken as a muffler. There is a big difference including the weight of the muffler is going to be much less than that of a catalytic converter.

Why Do Catalytic Converters Go Bad?

Catalytic converters have a life span of about 10+ years, but as they age they can get clogged, overheated, or damaged losing pieces of the honeycomb inside. When the catalytic converter starts to degrade this can affect the engine’s performance and will ultimately cause engine failure.
