How Much Does Catalytic Converter Replacement Cost?
Last updated: August 10, 2026 by the How Much Does That Cost? editorial team. Estimates are informational - see our methodology.
Catalytic converter replacement costs anywhere from $933 to $4,414 depending on the vehicle, with a commonly cited all-in average around $2,280-$2,480. The wide range comes down to the vehicle and the converter itself: parts alone can run $2,202 or more on some vehicles because of the platinum, palladium, and rhodium inside them.
Budget-conscious drivers on common vehicles can sometimes get a universal-fit aftermarket converter installed for $950-$1,500 all-in, while a direct-fit OEM part or a vehicle needing multiple converters (common on V6/V8 and dual-exhaust cars) can run $2,500-$4,500 or more. Catalytic converter theft has also become a major reason people search for this repair — see the FAQ below on insurance coverage.

Cost Breakdown
How a typical project budget breaks down by category.
| Category | Estimated Cost |
|---|---|
| Catalytic converter (part) | $400 – $1,400 |
| Labor (exhaust removal, welding/fabrication) | $200 – $500 |
| Oxygen sensor(s), if needed | $0 – $200 |
| Shop fees / emissions check | $20 – $100 |
What Affects the Cost
Number of converters needed
V6 and V8 engines, along with dual-exhaust vehicles, often use two catalytic converters instead of one, which can roughly double the parts cost.
Precious metal content
Catalytic converters contain platinum, palladium, and rhodium, and units with higher metal loadings cost more — this is also why prices can shift with precious metal market prices.
Aftermarket vs. OEM/direct-fit
Universal aftermarket converters are the cheapest option but may need extra cutting and welding to fit correctly; OEM and direct-fit units cost more but typically bolt straight into place.
Catalytic converter theft
Theft has become a major driver of this repair in recent years, since thieves can cut a converter out from under a parked car in just a few minutes to sell the precious metals inside. Replacement after a theft is usually similar in cost to a standard failure repair, plus exhaust pipe repair for the cut section.
Emissions law compliance
Federal and state emissions rules (including CARB rules in California and several other states) restrict which aftermarket converters can legally be installed on a given vehicle, which can limit how much cheaper you can go.
Related sensor issues
A failing oxygen sensor can damage a new converter, and a failing converter can throw off oxygen sensor readings, so both are sometimes replaced together to fix the underlying problem.
DIY vs. Hiring a Professional
Doing it yourself
DIY replacement is legal only with a compliant aftermarket converter for your specific vehicle and state — federal and CARB emissions rules restrict which units can be installed where — and the job also involves cutting and welding exhaust pipe, which most owners aren't equipped to do.
Hiring a professional
A shop knows which converters are legal for your vehicle and state, has a lift and welding equipment to remove and install the exhaust section cleanly, and can verify the repair passes emissions testing.
Bottom line: This is a professional job for nearly everyone — the combination of emissions law restrictions and exhaust welding work makes it impractical as a DIY project for most drivers.
Ways to Save
- Check with your insurer — comprehensive auto coverage often covers catalytic converter theft replacement, minus your deductible.
- Ask about a CARB-compliant aftermarket or universal converter instead of OEM if your state allows it, which can meaningfully cut the parts cost.
- Get quotes from muffler and exhaust specialty shops, which often charge less labor than a dealership for the same job.
- Consider having an anti-theft shield or cage installed after replacement to lower the odds of a repeat theft.
- If your vehicle uses two converters, ask whether both actually need replacing or just the failed one.
- Etch your VIN onto the converter and park in well-lit or covered areas to help deter theft in the first place.

Frequently Asked Questions
How much does it cost to replace a catalytic converter?
Catalytic converter replacement commonly averages around $2,280-$2,480 all-in, but the total range runs from about $933 on the low end to $4,414 or more, depending on the vehicle and number of converters needed.
Why are catalytic converters targeted by thieves?
Catalytic converters contain platinum, palladium, and rhodium, precious metals that scrap buyers pay well for, and a converter can be cut out from underneath a parked car in just a few minutes with basic tools.
Does insurance cover catalytic converter theft?
Comprehensive auto insurance coverage typically covers catalytic converter theft, minus your deductible, but liability-only policies do not, since theft isn't a collision.
Can I install a cheaper universal catalytic converter?
Only if it's legal for your specific vehicle and state — federal and California/CARB emissions rules restrict which converters can be installed where, so check compliance before choosing a budget option.
How do I know if my catalytic converter needs replacing?
Common signs include a check engine light with a catalyst-related code, a loud rattling sound from underneath the car, reduced engine power, a rotten-egg smell, or failing an emissions test.
