Catalytic converters and junk car value

How much does a catalytic converter add to a junk car's value?

It adds meaningfully, because converters contain precious metals, but the amount varies by model and moves with metal prices. Leave it on the car. A complete vehicle is priced as complete, and cutting the converter off can lower the offer by more than you could get for the part on its own.

What it is

A catalytic converter is part of the exhaust system. It uses platinum-group metals to change harmful exhaust gases into less harmful ones. That metal content is the reason it has value after the car is finished.

Why it matters in the offer

It is one of the four factors in a junk car quote, with weight, completeness and parts demand. Larger engines, trucks and some hybrids tend to have more of it, so the same factor pushes truck offers up. See the valuation guide for the full list.

Do not cut it off

A converter removed in a driveway is cut from a hot pipe, damages the exhaust and can start a fire. It also takes a complete car and makes it incomplete. If the car already lacks one, tell us. We would rather know than find out at the curb.

If the car was stripped

Some owners find the converter gone after a theft. That is a fact we need in the quote. A police report is worth having, and a car with a missing converter can still be sold. Send us the details and say what was taken.
