Catalytic Converter Replacement Cost: What to Expect in 2026

Catalytic converter replacement typically costs $950 to $2,500 in 2026, depending on your vehicle, the converter type, and local labor rates. A small economy car with an aftermarket unit might come in at $300 to $600 all-in. A luxury SUV or truck needing an OEM part can easily exceed $2,000 before tax. Parts are the biggest variable, since the converter contains platinum, palladium, and rhodium.

Average Cost Breakdown: Parts vs. Labor

Labor is usually $150 to $450 of the bill. Most mechanics charge $75 to $150 per hour, and the job takes one to three hours depending on where the converter sits. A unit tucked into a tight spot on an all-wheel-drive vehicle takes longer than one on a rear-wheel-drive truck with good clearance underneath.

Is It Worth Replacing a Catalytic Converter?

If the car is otherwise in good shape and worth more than the repair cost, replacement usually makes sense. A failing converter triggers a check engine light, causes the car to fail emissions and OBD-II readiness tests, hurts fuel economy, and can restrict exhaust flow enough to damage the engine in severe cases. On a high-mileage vehicle with several other problems, weigh the repair cost against what the car is actually worth. Most of the time, fixing the converter is the right call. Skipping it costs more in fuel, risks additional engine strain, and leaves the car unable to pass inspection in states that require it.

How to Cheaply Fix a Catalytic Converter Without Replacing It

There is no reliable cheap fix for a physically damaged or chemically poisoned converter. A few situations do have lower-cost solutions:

• Very early-stage clogging: Some fuel additive products (such as catalytic converter cleaner additives) occasionally help clear mild deposits. These work only in the earliest stages and will not fix a rattling or broken substrate.
• Faulty oxygen sensor triggering a P0420: A downstream O2 sensor that reads incorrectly can mimic a converter failure. Replacing the sensor ($50 to $150) is far cheaper than a new converter. Always get a proper diagnosis before replacing parts.
• Use an aftermarket converter: If replacement is needed, a CARB-compliant aftermarket unit from a reputable brand (Walker, MagnaFlow, Eastern Catalytic) costs $100 to $600 versus $300 to $1,500+ for OEM, with no meaningful reliability trade-off on most vehicles.

Removing or bypassing the converter is illegal under federal EPA regulations and will cause an immediate emissions failure.

Can I Drive with a Bad Catalytic Converter?

It depends on how far gone the converter is. One that is losing efficiency but still physically intact usually lets you drive for weeks without a breakdown. A converter with a broken substrate that is rattling or severely clogged can cause stalling, significant power loss, or a fire risk from extreme heat near the exhaust. The full picture is in our driving with a bad converter guide.

Factors That Change the Price

• Vehicle make and model: Honda Accords, Toyota Camrys, and similar high-volume cars have a deep aftermarket supply. Rare, European, or high-performance vehicles often require pricier OEM parts.
• Number of converters: Some V6 and V8 engines carry two catalytic converters, which can double the parts cost.
• OEM vs. aftermarket: OEM units from the dealer cost more but may be required to pass state emissions tests in California and the 15 CARB-adopting states.
• Geographic location: Shop labor rates in major metro areas are often 20 to 40 percent higher than in rural areas.
• Related repairs: A failing oxygen sensor or damaged exhaust flange discovered during the job adds to the total.

How Much Is a Catalytic Converter for an Acura TL?

The Acura TL uses a V6 engine with two catalytic converters. Aftermarket units run $150 to $400 each, while OEM parts from the dealer can reach $500 to $900 per unit. Total replacement cost for one converter, including labor, typically falls between $500 and $1,400. Replacing both at the same time doubles the parts cost but saves a full labor charge versus two separate visits.

Does Insurance Cover Catalytic Converter Replacement?

Standard auto insurance does not cover a converter that fails from age or normal wear. If yours was stolen, comprehensive coverage typically pays out after your deductible. Converter theft is now one of the most common auto insurance claims, driven directly by the precious metals inside. Some insurers offer specific theft endorsements for high-risk vehicles such as the Toyota Prius, Honda Element, and Toyota Tundra.

Can You Get a Quote Before Committing?

Yes, and you should. Call at least two or three local shops with your vehicle's year, make, model, and the diagnostic code (usually P0420 or P0430). Reputable shops will give you a written estimate. Get those before agreeing to any repair.

Frequently Asked Questions

Will a car pass emissions with a bad catalytic converter?
No. A faulty converter almost always triggers a check engine light and will cause the car to fail an emissions or smog test.

How long does a replacement catalytic converter last?
A quality replacement should last 70,000 to 100,000 miles or more with normal driving. Cheap aftermarket units from unknown brands may fail sooner.

What to Do Before Approving the Repair

Catalytic converter replacement typically costs $950 to $2,500, with parts as the bigger variable. Get multiple quotes, confirm whether OEM or aftermarket is legal in your state, and ask about any related repairs that might surface during the job. A few calls before you approve anything can save you $300 or more.
