Roughly how much does a catalytic converter replacement cost?
What drives the price
The converter itself is the biggest part of the cost, and original equipment units usually cost more than aftermarket ones. Some vehicles have converters built into the exhaust manifold, which adds labor. Regional emissions rules, such as stricter standards in some states, can limit which units are legal to install.
Labor time depends on how easy the exhaust system is to reach. Rusted bolts and welded joints can add hours, so get a written estimate that breaks down parts and labor.
Confirming the problem first
Before paying for a converter, confirm the cause of the code. A converter code can come from a bad oxygen sensor, an exhaust leak, or an engine misfire that damages the converter over time. Replacing the converter without fixing the root cause can waste money.
- Check oxygen sensor readings before and after the converter
- Look for exhaust leaks near the manifold and gaskets
- Confirm misfire codes are resolved
- Ask whether the warranty covers the part
Getting a fair quote
Ask at least two shops for itemized estimates, and ask whether the part is aftermarket or original equipment. Check whether the shop backs the work with a warranty. Current pricing changes often, so treat any figure you see online as a rough guide only.
Common mistakes
- Replacing the converter before confirming whether a sensor or misfire caused the code.
- Choosing the cheapest unit without checking whether it is legal in your state.
