Stealing catalytic converters is fast, easy, and requires no specialized tools. This makes it a ‘no brainer’ for petty criminals looking to cash in on skyrocketing prices of valuable metals. Within a few minutes, and a saw and/or wrench is all these crooks need to get off with the goods.

Catalytic converters are rich with precious metals including palladium, platinum, and rhodium. These metals are necessary for filtering vehicle exhaust and reducing carbon emissions. They also happen to be incredibly valuable on the open market, with each converter bringing in upwards of $200 each. In 15-20 minutes a criminal can hit 5 cars on the street or in a parking lot and be off with a cool $1000 worth of product for the day.

Unlike stealing a car, which could rise to the level of Grand Theft, stealing a catalytic converter carries a lesser charge of criminal damage to property and petty theft. This makes the risk to reward ratio an appealing one for many criminals.

Every vehicle in the USA has a catalytic converter. This means every parking lot, driveway, and garage are perfect targets for theft. Not just that, every vehicle, from sedans to sports cars and utility trucks have a converter.

Once stolen, it is difficult to trace back the part to a vehicle, making prosecution difficult. Most converters lack identification numbers.

The Cost of Replacing a Catalytic Converter After Theft

Due to Department of Transportation and Environmental Protection Agency laws, you cannot legally drive a vehicle without a catalytic converter.

If yours is stolen, you’ll be left footing a hefty bill. Not only will you be on the hook for the cost of replacement, but you’ll also likely incur additional expenses as a result of the damage caused to the vehicle. This could run you upwards of $2500 in some cases.

How to Tell if Your Catalytic Converter Has Been Stolen?

Given the location of the converter (under your vehicle), it is unlikely that you would notice it gone at first glance.

Below are a few telltale signs that your Catalytic Converter has been stolen:

  • You notice a loud, rumbling, or throaty noise when you turn on the engine

  • Accelerating sounds like a racecar or monster truck

  • Sputtering sounds when changing speed

  • A gaping space between your tailpipe and the middle of your exhaust

  • Odd smells from fumes
