Catalytic converters are among the most expensive single parts on a vehicle, thanks to the precious metals inside them. Whether yours failed naturally or was stolen (catalytic converter theft has surged in recent years), the replacement cost is significant.
Cost Breakdown
| Type | Parts | Total Installed |
|---|
| Aftermarket (universal fit) | $200–$600 | $500–$1,200 |
| Aftermarket (direct fit) | $400–$1,200 | $800–$2,000 |
| OEM | $800–$2,500 | $1,200–$3,500 |
California emissions vehicles: If your car was sold in California (or is registered there), you must use a CARB-compliant converter, which costs 2-3x more than a federal converter. There is no legal workaround for this.
Theft Replacement
If your converter was stolen, file a police report first, then contact your insurance. Comprehensive coverage typically covers catalytic converter theft minus your deductible. Some states have passed laws requiring salvage yards to verify converter ownership, but theft remains rampant on high-target vehicles (Toyota Prius, Honda Accord, Ford F-150).

Frequently Asked Questions
How much does it cost to replace a catalytic converter?
Catalytic converter replacement costs $500 to $1,200 installed with a universal-fit aftermarket unit, $800 to $2,000 with a direct-fit aftermarket unit, and $1,200 to $3,500 for OEM. The part is most of the bill, so the OEM versus aftermarket choice matters more than the shop labor rate. Across the 803 auto repair quotes QuoteScore has scored, 55.9% scored under 50, meaning at least one line was priced above the normal market range for that repair and region, so ask for the parts and labor split before approving anything.
Why are catalytic converters so expensive?
Catalytic converters contain precious metals — platinum, palladium, and rhodium — that serve as catalysts to reduce harmful emissions. Rhodium alone costs over $4,000 per ounce. These metals make converters expensive to manufacture and also a target for theft.
