Are you experiencing car issues? Cost research is a good idea before hiring a mechanic for catalytic converter replacement. You can expect to pay $400+, but your mechanic might have a higher or lower quote. The cost of replacing your catalytic converter depends on car type and project complexity.
Defining the catalytic converter
A catalytic converter is an important car part. It’s fitted inside your exhaust pipe before the muffler to reduce harmful emissions and turn unused fuel particles into harmless gases. The outside of a catalytic converter has a steel shell, and the inside looks a bit like a honeycomb. This "honeycomb" does all the work of filtering gases.
Catalytic converter prices for different car models
Depending on availability, you can get a new catalytic converter or save some money by buying a secondhand/reconditioned one. Your mechanic will advise you on specific costs and help you source the right parts. The average cost of replacing a catalytic converter is $945 to $2,475. However, if you’re looking for a converter for a specific brand, refer to the list below:
Car make and model |
Catalytic converter price |
Ford F-150 |
$1,280 |
Honda Accord |
$1,970 |
Honda Civic |
$1,560 |
Nissan Altima |
$1,380 |
Toyota Corolla |

Chevrolet Silverado |

You can also get universal catalytic converters. Their prices depend on unit shape and size. They can be a good option if your converter is difficult to source in the US and is no longer manufactured.
Catalytic converter replacement costs
You can estimate your total catalytic converter replacement costs with this simple formula: converter cost + (hourly rate x total time) = total cost. First, check the table above for the cost of your converter. Second, add it to the product of your mechanic’s hourly rate* and expected project duration.Â
*Mechanics usually charge $17 to $23 per hour. If your mechanic is a specialist or works for a dealership, they’ll be on the higher end of the scale. Private and independent mechanics tend to charge lower hourly rates. |

Signs of catalytic converter damage
The only way to know if your catalytic converter needs replacing is to consult a mechanic. They’ll check your car and run some tests. Before then, here are some warning signs:
Car issue | Description |
Your vehicle isn’t performing like it used to | If your converter isn’t functioning well, it will make your engine dirty and sluggish. |
Your check engine light is on | This could mean a lot of things, including converter damage. |
Your exhaust is smelly | If you smell rotten eggs coming from your car’s exhaust, perhaps your catalytic converter isn’t burning all the particles and pollutants properly. |
You refuel your car often | If you’re going through fuel a bit faster than usual, there’s something wrong with your engine, and this might be due to an ineffective converter. |
The process of catalytic converter replacement
When you book a mechanic to replace your catalytic converter, they will:
Use their equipment to confirm if your catalytic converter is the problem
Raise your car to work underneath it
Unclamp, unbolt, or extract (depending on the make and model) your old catalytic converter from your exhaust pipe
Fit your new convert securely
Lower your car and run the engine
Perform tests, including a road test, to make sure it’s working properly
Other services after replacing your catalytic converter
Your mechanic can look at your car's other parts and offer more services. You can request the following:
Service | Inclusions |
General car service | an oil and filter change, a fluid top-up, a safety inspection, and a brake check |
Full car service | spark plug replacement, component QA, logbook entries, and suspension adjustment |

Usually, catalytic converters fail due to engine problems causing too much heat. Using the wrong fuel can also cause converter failure.
Your converter breaks down exhaust fumes from your car. If it breaks, your car’s exhaust will be a lot smellier than usual. Moreover, your engine will run less smoothly.
Many catalytic converters last indefinitely (longer than many other parts that need replacing). Still, if you experience engine or exhaust issues, you might need a new catalytic converter. Don't delay the replacement for too long because it can impact your engine.
