Catalytic Converter Replacement Cost in 2026: Price Guide

A catalytic converter replacement costs about $1,000 to $3,500 in 2026, parts and labor included. Luxury cars can run $5,000 to $10,000 or more. The part is most of the bill: an aftermarket converter costs $400 to $1,200 and an OEM converter $800 to $2,500, and most jobs take 1 to 3 hours of labor.

Below you will find costs by vehicle, how to tell a failed converter from a cheaper sensor problem, what to do after a theft, and who pays: car insurance, a warranty or you.

Catalytic Converter Replacement Cost at a Glance

Most drivers pay $1,000 to $3,500 to replace a catalytic converter. Where you land depends on your car, the type of part and how hard the converter is to reach.

What you pay for	Typical cost
Aftermarket converter (part only)	$400 to $1,200
OEM converter (part only)	$800 to $2,500
Labor	1 to 3 hours at $150 to $300 per hour
Total, most cars	$1,000 to $3,500+
Total, luxury cars	$5,000 to $10,000+
Anti-theft shield, installed	$150 to $400

Parts vs Labor Cost

Parts: The converter itself is the biggest cost. A quality aftermarket converter runs $400 to $1,200. An OEM (original equipment manufacturer) converter costs $800 to $2,500, and specialty or exotic cars cost more.

Labor: Most shops charge $150 to $300 per hour, and the job usually takes 1 to 3 hours. A bolt-on converter that is easy to reach sits at the low end. A converter that is welded in, built into the exhaust manifold or hidden behind other exhaust parts takes longer.

Why Catalytic Converter Prices Vary So Much

Make and model: Larger engines and luxury brands use bigger converters with more precious metal inside.
Number of converters: Some engines, especially V6 and V8 engines, have more than one. Shops may list them as bank 1 and bank 2. Ask which one failed and whether the quote covers one or all of them.
OEM or aftermarket: Aftermarket parts usually cost 30% to 50% less than OEM.
Access and labor rates: Hard-to-reach converters take more hours, and hourly rates differ by region and shop type.
Extra damage: After a theft or a long-ignored engine problem, pipes, gaskets and oxygen sensors may need replacing too.

Catalytic Converter Replacement Cost by Vehicle

Here is what owners of common vehicles can expect to pay for parts and labor combined.

Vehicle	Average Cost	Why it costs this much
Toyota Prius	$1,500 to $2,200	Higher due to size/design
Honda CR-V	$1,200 to $2,000	Mid-range
Toyota RAV4	$1,300 to $2,100	Mid-range
Ford F-150	$1,000 to $1,800	Varies by generation
Dodge Caravan	$800 to $1,500	Relatively accessible
Jeep Wrangler	$1,100 to $1,900	Moderate difficulty
BMW 3 Series	$2,000 to $3,500	Luxury premium
Nissan Altima	$900 to $1,600	Standard sedan

These are 2026 estimates. Your price depends on the model year, engine, the number of converters and local labor rates. Owners of a Honda CR-V or Toyota RAV4 can see other common repairs in our Honda CR-V problems by year and Toyota RAV4 problems by year guides.

OEM vs Aftermarket Catalytic Converter: Which Should You Buy?

There is no single right answer. It depends on your car, your budget and how long you plan to keep it.

OEM converters are made by your vehicle's manufacturer. They fit exactly, keep the emissions system working as designed and usually come with a parts warranty. They cost the most.
Aftermarket converters are made by other companies and usually cost 30% to 50% less. Quality varies a lot. A converter from a known brand such as Bosal, Walker or Magnaflow can work almost as well as OEM. A cheap no-name part may fail within a year and send you back to the shop.

Our take: If your car is still under its factory warranty or you are financing it, choose OEM. If you own the car outright and money is tight, a quality aftermarket converter from a trusted brand is a sensible choice. Before you buy any aftermarket part, ask the shop to confirm it is legal for emissions rules in your state.

Signs of a Bad Catalytic Converter

Not every replacement comes from theft. Converters also wear out or get damaged, most often on high-mileage cars and cars that missed regular maintenance. Watch for these warning signs:

Check engine light: often the first indicator
Reduced fuel economy: running less efficiently
Loss of power: especially during acceleration
Rotten egg smell: sulfur odor from the exhaust
Excessive heat: under the vehicle near the converter
Loud rattling: the internal honeycomb structure breaking apart
Failed emissions test: clear indicator of converter problems

What Causes a Catalytic Converter to Fail

A converter rarely fails on its own. It usually fails because of a problem upstream in the engine. Fix that problem first, or the new converter can fail the same way.

Engine misfires send unburned fuel into the converter, where it overheats and melts the inside.
Burning oil or coolant coats the inside of the converter. A worn engine or a leaking head gasket are common causes.
A faulty oxygen sensor can make the engine run too rich and overheat the converter.
Physical damage from road debris, speed bumps or a theft attempt can crack the converter or its pipes.

Can You Keep Driving With a Bad Catalytic Converter?

You can drive a short distance, but do not put the repair off. A clogged converter traps exhaust, cuts power and over time can damage the engine. If the check engine light flashes, or you smell rotten eggs and the car loses power, stop driving and get it checked. A small repair now is cheaper than engine damage later.

Catalytic Converter Theft: Why Thieves Target It

Catalytic converters contain precious metals that scrap buyers pay for, and a thief with a battery-powered saw can cut one out in minutes. Thieves often damage the exhaust pipes, oxygen sensor wiring or nearby parts on the way, which can turn a $1,500 repair into a $2,500+ bill.

Cars Most Likely to Lose Their Converter

Toyota Prius: top target by a landslide, partly because they have larger converters and easier access; thieves specifically target Priuses due to familiarity with removal
Honda CR-V: see our Honda CR-V Problems by Year guide for more common issues; high ground clearance makes access simple
Ford F-150 and other trucks: higher clearance makes them easier to jack up; commercial use means longer parking periods in exposed areas
Toyota RAV4: another popular SUV that thieves love (check out our Toyota RAV4 Problems by Year guide); common enough that thieves know the exact location
Dodge Caravans: easier exhaust access and lower profile make them targets; minivans often sit in parking lots for extended periods
Jeep Wranglers: similar accessibility issues; popular in regions where vehicle-on-blocks thefts are common

If you drive one of these and park on the street, a shield and smarter parking are worth the small cost.

Stolen Catalytic Converter: Who Pays?

A stolen converter costs the same $1,000 to $3,500+ to replace as a failed one. Car insurance covers theft only if you have comprehensive coverage. Liability-only policies do not pay for it. Your deductible applies, so for a cheaper car the claim may not be worth filing.

An extended car warranty does not pay for theft. A vehicle service contract covers mechanical and electrical breakdowns, while theft and vandalism are car insurance claims. See extended warranty vs car insurance for how the two split the work.

After a theft, do this:

File a police report. Your insurer will ask for it.
Call your car insurance company to start a comprehensive claim.
Do not drive far. The car will be very loud and exhaust gases can leak.
Ask the shop to check the oxygen sensors, wiring and pipes for damage, so the claim covers all of it.

How to Prevent Catalytic Converter Theft

A catalytic converter shield ($150 to $400 installed) is the most effective step. It turns a quick theft into a slow, noisy job, which is often enough to make thieves move on. Good shields are made of stainless steel or heavy-gauge aluminum, bolt to the underside of the car and do not affect how it runs. Some are made for specific models such as the Prius.

Other ways to lower the risk:

Park in a garage, or in well-lit, busy spots.
Install an alarm that alerts you to tampering under the car.
Etch your VIN on the converter so it is harder to sell.
Avoid leaving the car for long periods in unattended commercial lots.

How to Lower Your Catalytic Converter Replacement Cost

Confirm the diagnosis. Ask the shop to rule out a bad oxygen sensor, an exhaust leak or a misfire before you pay for a new converter.
Get at least three quotes. Shopping around can save $300 to $500. See more ways to save on repairs.
Compare independent shops with the dealer. Independent shops often charge less for the same job. A dealer may still be the right choice while your car is under factory warranty.
Check your factory warranty first. On newer cars the converter is often covered by the manufacturer's emissions warranty, which can last longer than the basic warranty. Ask a dealer before you pay.
Ask about the repair warranty. A good shop warrants the part for at least a year and the labor for at least 30 days. If it will not, keep shopping.
Fix the cause, not just the converter. If a misfire or an oil leak killed the old converter, it will kill the new one too.
Do not wait. Driving with a failing converter can damage the engine. It is expensive now, but it gets worse later.

Does an Extended Warranty Cover a Catalytic Converter?

Sometimes, and only for a breakdown, never for theft. Whether a failed converter is covered depends on the contract. Many service contracts list the exhaust system as an exclusion, so read the sample contract or ask before you buy if this repair matters to you. Learn more in what an extended warranty covers and exclusionary vs inclusionary coverage.

The bigger risk is often what killed the converter. Misfires, burning oil and a leaking head gasket point to engine trouble, and engine repairs cost far more: an engine replacement runs $3,000 to $7,000+ and a head gasket repair $1,500 to $3,500.

With CoverageX, every plan includes the engine, transmission and drivetrain. The Essential plan covers those parts, including seals and gaskets. Signature adds electrical systems, air conditioning and suspension, and Executive is exclusionary: everything is covered unless the contract lists it as excluded. See how CoverageX works. New to these plans? Read our extended protection plan guide.

When it is worth it: your factory warranty has ended, you plan to keep the car for years and a $3,000+ engine or transmission bill would hurt your budget.

When to skip it: the car is still under factory warranty, you could pay a large repair bill from savings, or your only worry is the converter itself. Read when not to buy an extended warranty and compare what an extended car warranty costs.

Coverage starts 30 days after purchase and after 1,000 miles, and problems that exist before then are not covered. A plan helps with future breakdowns, not a converter that is already failing.

Protect the bigger repairs. A failed converter is often a sign of engine trouble, and engine and transmission repairs cost thousands. Every CoverageX plan covers the engine, transmission and drivetrain, pays the repair shop directly and includes 24/7 roadside assistance.

Catalytic Converter Replacement: Frequently Asked Questions

How much does it cost to replace a catalytic converter?

Most drivers pay $1,000 to $3,500 for parts and labor. The part costs $400 to $1,200 aftermarket or $800 to $2,500 OEM, and labor runs 1 to 3 hours at $150 to $300 per hour. Luxury cars can cost $5,000 to $10,000 or more.

Why are catalytic converters so expensive?

They contain precious metals that clean the exhaust. Those metals make the part costly to build and attractive to thieves. Bigger engines need bigger converters, and some cars have more than one.

How long does a catalytic converter replacement take?

Most replacements take 1 to 3 hours of shop time. A bolt-on converter is quicker. A welded-in converter, or one that requires removing other exhaust parts, takes longer. If the part is in stock, many shops finish the same day.

Can I drive with a bad catalytic converter?

Only for a short distance. A clogged converter cuts power and can damage the engine over time. If the check engine light flashes or the car loses power, stop driving and have it checked.

Can a bad oxygen sensor mimic catalytic converter failure?

Yes. The oxygen sensors measure how well the converter works, so a failing sensor can set the same warning code. A sensor costs far less than a converter, so ask the shop to test the sensors before replacing the converter.

Is an OEM or aftermarket catalytic converter better?

OEM fits exactly and lasts, but costs more. A quality aftermarket converter costs 30% to 50% less and suits an older car you own outright. Avoid cheap no-name parts, and make sure any aftermarket part is legal in your state.

Does car insurance cover a stolen catalytic converter?

Yes, if you have comprehensive coverage. Liability-only policies do not cover theft, and your deductible applies. File a police report first. See extended warranty vs car insurance.

Does an extended car warranty cover a catalytic converter?

It never covers theft, and it covers a failed converter only if your contract includes it. Many contracts exclude the exhaust system, so check the contract before you buy. Engine problems that often ruin a converter, such as a bad head gasket, are covered by every CoverageX plan.

Which cars are most likely to have their catalytic converter stolen?

The Toyota Prius is the top target. The Honda CR-V, Toyota RAV4, Ford F-150 and other trucks, Dodge Caravan and Jeep Wrangler are also common targets because their converters are easy to reach. A shield costs $150 to $400 installed.

The Bottom Line

A catalytic converter replacement costs $1,000 to $3,500 for most cars. Confirm the diagnosis, fix the engine problem that caused the failure, get several quotes and choose OEM or a quality aftermarket part based on how long you will keep the car. If your car is a common theft target, a $150 to $400 shield costs far less than a stolen converter. For other big repair bills, see our car repair cost guides.
