Catalytic Converter Replacement cost
Catalytic Converter Replacement typically costs $1,150 to $3,250 at an independent shop, parts and labor included, and most shops book about 1 to 3 hours for the job.
The catalytic converter cleans the exhaust before it leaves the car. It is an expensive part because it contains precious metals, so it is worth confirming the converter itself has failed and not just a sensor. A converter that fails early usually has an underlying cause, like an unresolved misfire, that should be fixed first.
Typical cost
Parts and labor at an independent shop. Your exact price depends on the car, your area, and the parts chosen.
What the job involves
- Confirm the converter has failed, not an oxygen sensor or an exhaust leak
- Fix any root cause, such as a misfire, so the new converter lasts
- Remove the old converter (welded or bolted in)
- Install the new converter, and oxygen sensors if needed
- Clear the codes and verify the repair
What moves the price
- OEM versus aftermarket versus a CARB-compliant unit (required in California)
- How many converters the vehicle has
- Precious-metal pricing, which drives the part cost
- Whether oxygen sensors are replaced at the same time
Signs you may need it
- A P0420 or P0430 check-engine code
- A failed emissions or smog test
- A rotten-egg or sulfur smell from the exhaust
- Sluggish acceleration or a rattle from under the car
How long it lasts
A converter should last the life of the car, so an early failure points to a root cause worth finding.
