Catalytic converter replacement costs $800 to $2,500 in 2026
Most cars land between $800 and $2,500 installed, with luxury and hybrid models above $3,000. The part is most of the bill: an EPA compliant converter runs $400 to $1,500, a CARB compliant one for California rules $1,200 to $3,000, and an OEM part $800 to $2,500. Labor is usually 1 to 3 hours.

These rows are our estimate. We took the typical national range and adjusted it for local labor costs, which run about 20 percent lower in the cheapest states and about 30 percent higher in the dearest ones. The state also changes the part itself here, not just the labor. CARB states pay far more for the converter.
Why California pays more, and what to do after a theft
A catalytic converter must meet the emissions rules where the car is registered. In most of the country an EPA compliant converter is legal, at about $400 to $1,500 for the part. California and the states that follow its rules require a CARB compliant converter, which carries more precious metal and costs about $1,200 to $3,000. A shop in a CARB state that fits a cheaper federal converter can leave you with a car that fails inspection.
If the converter was stolen
Converter theft is common because of the metals inside. File a police report, then call your insurer. Ask whether your comprehensive coverage pays for theft and what your deductible is. After the repair, ask the shop about a shield or cage, and park in a garage or a lit area if you can.
Check the cause first
A converter usually fails because something upstream failed: a misfire, an oil burning engine or a bad oxygen sensor. If that is not fixed, the new converter can fail too.
Why this costs more in 2026
Converters are made of precious metals and ship long distances, and exhaust work adds labor at this year's rates.
The short version is oil. Diesel passed $6 a gallon on the AAA national average for the first time on September 11, 2026. A year earlier it was about $3.70 (CBS 8 reporting AAA). That lands in trip charges, deliveries and anything made from petroleum. Quotes are being held open for shorter periods this year, so ask for the expiry date in writing.
How to judge the quote in your hand
- Ask EPA or CARB compliant. It must match your state.
- Ask OEM or aftermarket, and the warranty on each.
- Ask what killed the old one. Fix the cause first.
- Ask how many converters your engine has.
- Get the part number on the quote.
Ways to pay less
- Use a legal aftermarket converter if your car and state allow it.
- Check your emissions warranty. Converters often carry a long federal warranty on newer cars.
- Use an exhaust specialist for a second quote.
- Claim theft on comprehensive if you have it.
