Catalytic converter replacement is one of the most expensive emissions repairs because the converter itself contains precious metals. Here is exactly what to expect, what drives the price up, and when an aftermarket unit is a smart choice.
OEM converters are pricey because of platinum, palladium, and rhodium content. Aftermarket and CARB-compliant California units cost more.
Labor depends on rust, exhaust design, and whether oxygen sensors transfer over. Shops typically book 1.5-3 hours.
| Vehicle Class | Typical Range | Notes |
|---|---|---|
| Compact car (Civic, Corolla) | $700 - $1,400 | Aftermarket federal unit typical |
| Sedan (Camry, Accord) | $900 - $1,800 | Often two converters on V6 |
| SUV / Crossover (RAV4, CR-V) | $1,000 - $2,200 | Heat shields add time |
| Truck (F-150, Silverado) | $1,200 - $2,800 | Two converters, more labor |
| Luxury / European (BMW, Audi) | $1,800 - $4,000+ | OEM strongly recommended |

You can usually drive short distances, but a clogged converter restricts exhaust flow and overheats the engine. If you smell sulfur, hear a rattle, or lose power, get it fixed soon. Driving on a partly clogged cat will fail emissions and may damage other parts.
Sometimes. Cheap universal converters often re-trigger P0420 within months. Direct-fit units from Walker, Magnaflow, and Eastern Catalytic are designed to pass OBD2 monitors and usually clear the light permanently.
A factory converter typically lasts 100,000-150,000 miles. Most failures are caused by upstream problems (oil burning, misfires, rich fuel mix) rather than the converter itself wearing out.
Just the converter is cheaper if the rest of the exhaust is solid. If your muffler and pipes are rusted, a cat-back replacement at the same time is often only $200-$400 more in labor.
