Catalytic converter replacement costs between $800 and $2,500 for most vehicles, depending on your car's make and model, whether you use an original part or an aftermarket one, and whether you do the work yourself or pay a shop

The largest variable is the part itself. Original equipment manufacturer (OEM) converters — the ones made by your car's manufacturer — typically cost $500 to $2,200 before labor. Aftermarket converters, made by third-party companies, run $300 to $900. The difference reflects the materials inside: catalytic converters contain platinum, palladium, and rhodium, and OEM parts usually contain more of these precious metals, which is why they last longer and cost more.

Labor adds $100 to $300 in most shops, though some charge flat rates of $150 to $500 depending on how difficult the converter is to reach on your specific vehicle. A few cars — particularly some Subarus and Audis — have converters mounted directly to the engine, which takes longer to remove and costs more to replace. Others have the converter bolted to the exhaust system underneath, which is faster work.

Key Takeaways

  • OEM catalytic converters cost $500 to $2,200 before labor; aftermarket converters cost $300 to $900, and the difference is the amount of precious metals inside.
  • Labor typically runs $100 to $300, but some shops charge $150 to $500 flat rates depending on how accessible the converter is on your vehicle.
  • Luxury and performance vehicles often have converters that cost $1,500 to $2,500 because they contain more precious metals and are harder to access.
  • Getting quotes from three shops before committing will show you the range for your specific car, since prices vary widely by location and shop.
  • Some independent shops charge less than dealerships for the same OEM part, so comparing labor rates separately from parts costs matters.

How the type of converter affects the price

An OEM converter is built to your car's exact specifications and will pass any emissions test. It comes with a warranty — usually three years or 36,000 miles from the manufacturer — and will typically last 80,000 to 100,000 miles before needing replacement again. You pay more upfront, but you get a longer lifespan and the certainty that it fits perfectly.

An aftermarket converter costs less because it is a generic design that fits multiple vehicle models, not just yours. It will pass emissions tests in most states, but some aftermarket converters are designed to meet minimum standards rather than exceed them. They typically last 50,000 to 80,000 miles. Some shops warranty them for one year; others offer no warranty at all. If you plan to keep the car for a long time, the lower upfront cost may mean a second replacement sooner.

A few shops sell used converters salvaged from junked vehicles. These cost $200 to $400 but carry no warranty and no may provide of how many miles remain before failure. Used converters are a gamble unless you know the mileage on the original vehicle.

What your vehicle's make and model costs

Domestic vehicles — Ford, Chevrolet, Dodge, GMC — typically have the cheapest converters. An OEM Ford or Chevy converter usually costs $600 to $1,200, and labor is straightforward because these vehicles are common and mechanics know them well.

Japanese brands like Honda, Toyota, and Nissan fall in the middle. OEM converters for these vehicles run $800 to $1,400. They are still common enough that labor is predictable, usually $150 to $250.

Luxury and European vehicles — BMW, Mercedes, Audi, Volkswagen — have the highest costs. OEM converters for these cars run $1,500 to $2,500 because they contain more precious metals and are engineered to tighter tolerances. Labor is also higher, often $300 to $500, because the converter is harder to access and requires more specialized knowledge. A BMW 3 Series converter replacement can easily exceed $3,000 total.

Hybrid vehicles like the Prius have converters that cost more than their gas-only equivalents because they run hotter and require more durable materials. Expect to pay 20 to 40 percent more for a hybrid converter than for a comparable non-hybrid model.

Labor costs at different types of shops

A dealership charges the most labor, typically $200 to $500 per hour, and a converter replacement usually takes one to three hours. A dealership will use only OEM parts and will warranty the work for the length of your vehicle's factory warranty. If something goes wrong, you have recourse through the manufacturer.

An independent repair shop usually charges $100 to $250 per hour and can install either OEM or aftermarket converters. Many independent shops will warranty their labor for one year. They often charge less than dealerships for the same work because their overhead is lower. The trade-off is that if a problem arises, you are dealing with a single shop rather than a manufacturer's warranty system.

A chain shop like Firestone or Midas typically charges $150 to $300 per hour and stocks mostly aftermarket converters. They often advertise flat rates — for example, $400 to $600 total for a converter replacement on common vehicles — which can be cheaper than paying hourly labor. These shops usually warranty labor for one year and parts for one to three years, depending on the converter brand.

A muffler shop specializes in exhaust work and may charge less than a general repair shop because they do this work constantly. Expect $100 to $200 per hour, and they often have aftermarket converters in stock. Quality varies widely, so ask for references or check online reviews before committing.

What affects how long the job takes

A straightforward converter replacement on a common vehicle — a Honda Civic, Toyota Camry, or Ford F-150 — takes 45 minutes to two hours. The converter bolts to the exhaust system, the bolts come loose without much trouble, and the new one goes in quickly. Labor on these vehicles is usually $150 to $250.

A difficult replacement takes two to four hours. This happens when the converter is welded to the exhaust pipe instead of bolted, when it is mounted directly to the engine and requires removing other parts to reach it, or when the bolts are rusted and difficult to remove. Some Subarus, Audis, and older luxury vehicles fall into this category. Labor can reach $400 to $600.

If the bolts are severely corroded or the converter is stuck, a shop may need to cut it out rather than unbolt it, which adds time and cost. This is more common in vehicles from cold climates where road salt corrodes metal faster. Ask the shop to inspect the converter before quoting labor; they can tell you whether cutting will be necessary.

Getting an accurate quote for your car

Call or visit three shops with your vehicle's year, make, model, and current mileage. Ask for a quote that separates the parts cost from the labor cost, and specify whether they are quoting OEM or aftermarket. A good quote will look like this: "OEM converter, $1,100; labor, $200; total, $1,300." A vague quote that just says "$1,500" does not tell you what you are paying for.

Ask whether the quote includes a warranty on the part and on the labor. A one-year labor warranty is standard; a three-year parts warranty on an OEM converter is standard. If a shop offers no warranty, ask why — it may be because they use used parts or because they are cutting corners.

Ask how long the job will take and when they can schedule it. If a shop says they can do it the same day, they likely have the part in stock and can move quickly. If they need to order the part, add two to five business days to the timeline.

Frequently Asked Questions

Can I drive with a bad catalytic converter?

Yes, but your car will fail an emissions test and you may see a check engine light. Driving on a severely damaged converter can reduce fuel economy by 20 to 40 percent and may cause the engine to overheat. Most states require you to fix it before renewing your registration, so delaying the repair usually costs you more in the long run.

Is it cheaper to replace the converter myself?

If you have welding equipment and exhaust work experience, you might save $150 to $300 in labor. However, most DIY attempts fail because converters are difficult to access, bolts are often corroded, and improper installation can cause exhaust leaks. Unless you have done this work before, a shop will do it faster and more reliably.

Will an aftermarket converter pass inspection?

Most aftermarket converters pass emissions tests in most states. However, some states have stricter standards, and a few require OEM converters for vehicles under a certain age. Check your state's emissions rules before buying an aftermarket converter, or ask the shop whether it will pass in your area.

How do I know if my converter needs replacement?

A check engine light with a code related to the catalytic converter is the clearest sign. Other signs include a rattling sound from underneath the car, a rotten egg smell from the exhaust, or a sudden drop in fuel economy. A shop can scan your vehicle's computer to confirm whether the converter is the problem.

Does the warranty on a converter matter?

Yes. An OEM converter with a three-year warranty gives you protection if it fails prematurely. An aftermarket converter with a one-year warranty is riskier if you plan to keep the car for several years. Factor the warranty length into your decision, especially if you are choosing between a cheap aftermarket part and a more expensive OEM part.
