How much does it cost to replace a catalytic converter on a Honda?

Typically, you should budget roughly $1,000 to $3,000 for a complete catalytic converter replacement on a Honda, depending on model, whether you choose OEM or aftermarket parts, and local labor rates.

What determines the price

Several factors influence the final bill beyond the base part price. The number of catalytic converters, the choice between OEM vs aftermarket parts, and the shop’s labor rate all play major roles. Additional work, such as replacing oxygen sensors or sealing gaskets, can also add to the cost.

• Number of converters: Some Hondas have one catalytic converter, while others have two; replacing both costs more.


• Part type: OEM (direct-fit Honda parts) typically carry higher prices than aftermarket or universal catalytic converters.


• Labor rate and location: Urban areas and specialty shops tend to charge more per hour than rural or independent shops.


• Support components: Oxygen sensors, gaskets, and exhaust piping may need replacement alongside the converter.


• Emissions compliance: In some regions, additional tests or checks can influence final costs.


• Warranty or recall status: If the vehicle is under warranty or a recall covers the replacement, costs can be reduced or eliminated.

Prices vary by model, region, and shop, so use this as a general guide and obtain multiple written estimates for your specific Honda.

Typical price ranges by part type

Before comparing quotes, consider how the part choice affects the total installed cost. The following ranges reflect common real-world scenarios for Hondas.

• OEM direct-fit catalytic converter (Honda-branded part): Parts typically $900–$2,000; labor usually $150–$300; total installed often $1,050–$2,300, depending on local rates and vehicle model.


• Aftermarket or universal catalytic converter: Parts often $200–$600; labor $150–$350; total installed about $350–$950. Note that universal units may require welding and precise sensor placement, which can raise labor time.


• Used or remanufactured catalytic converter: Parts typically $50–$250; labor $100–$350; total around $150–$600. Availability and reliability vary; these options may not pass emissions tests in all areas.


• Two-cat configurations or premium models (where applicable): If two converters must be replaced, totals can run higher, roughly $1,800–$3,500 depending on part type and labor.

These ranges are approximate and depend on your exact Honda model, local labor markets, and whether additional components must be replaced. Always verify what is included in a quote—part, labor, sensors, gaskets, and any required welding.

Factors that influence the final price

Beyond the itemized list above, several practical considerations affect the bottom line. Understanding them helps in negotiating and budgeting.

• Vehicle model and engine type: Some Civics, Accords, or CR-Vs have different exhaust configurations that change part costs and labor time.


• Specific part selection: OEM parts offer exact fit and warranty coverage but cost more; aftermarket options can save money but may affect fit or longevity.


• Shop location and reputation: Dealer service departments tend to be more expensive than independent auto shops, though they may offer OEM expertise.


• Sensor and auxiliary work: Replacing aging oxygen sensors or resealing flanges can add to the labor and part costs.


• Warranty and recalls: If a replacement is covered under warranty or a factory recall, your out-of-pocket cost may be reduced or zero.


• Emissions testing requirements: Some states require inspections that can affect the acceptance of a replacement and potential fees.

To avoid surprises, request a written, itemized quote that separates parts, labor, and any sensor or gasket costs, and ask for an estimated timeline for completion.

Summary

Replacing a catalytic converter on a Honda is a substantial repair with a broad price range. Expect installed costs from about $1,000 to $3,000, with OEM parts at the higher end and aftermarket or used parts offering savings. The main drivers are the number of converters, part type, labor rates, and whether additional sensor work is needed. Always obtain multiple quotes, verify what is included, and check warranty or recall options to determine the best value for your specific vehicle.

What is the cheapest way to replace a catalytic converter?

The cheapest way to fix a catalytic converter is to replace it with a universal one, which can cost about $200-$300 if installed by a muffler shop. Other cheaper options include trying a catalytic converter cleaner or addressing underlying issues like exhaust leaks before considering replacement.

Universal catalytic converter replacement 

• A muffler shop can weld in a universal replacement converter, which is cheaper than a direct-fit model. 
• This method may require some modification to fit your vehicle's exhaust system. 
• Cost: Around $200-$300 for the part and labor. 

Cheaper alternatives to full replacement 

• Cleaners: Products designed to clean the converter may work for soot clogs but are not guaranteed to solve the problem. 
• Fix underlying issues: Before replacing the converter, check for other exhaust problems, like leaks or bad gaskets, which can be cheaper to fix and may restore proper function. 
• Professional diagnosis: A mechanic can use an OBD-II scanner to identify diagnostic trouble codes (DTCs) to determine the root cause of the issue and whether replacement is necessary. 

DIY options and considerations

• DIY replacement: You can save on labor costs by replacing a stolen or damaged converter yourself using a universal kit, as shown in this YouTube video. 
• O2 sensor spacers: These can trick the engine computer into thinking the catalytic converter is working properly, but this is often a temporary fix and may be illegal, notes this YouTube video. 
• Important note: If the internal honeycomb is damaged, a cleaner or spacer will not fix the problem, and replacement is the only way to solve it.

Is it worth replacing a catalytic converter?

Yes, it is worth replacing a catalytic converter because it is essential for your car's performance, longevity, and legality. Driving without one can lead to poor acceleration, reduced engine performance, lower fuel efficiency, and environmental damage. Additionally, you will likely not be able to pass an emissions test, which is required to legally register and drive your car in most places.

Reasons to replace a catalytic converter

• Legality: You cannot pass an emissions test without a properly functioning catalytic converter, and many states require one for registration. 
• Vehicle performance: A failed or clogged converter can cause a significant loss of engine power, leading to poor acceleration and slower top speeds. 
• Engine and exhaust damage: Driving with a bad converter can cause damage to other parts of the engine and exhaust system, such as overheating or causing more significant engine stress. 
• Environmental impact: The converter's primary function is to convert toxic pollutants into safer gases, so a replacement is necessary to prevent releasing harmful fumes into the environment. 
• Fuel efficiency: A failing converter can negatively impact your gas mileage, leading to higher fuel bills. 
• Resale value: A car without a catalytic converter will have a lower resale value and may be difficult to sell.

What to consider before replacing

• Diagnosis: Have a mechanic properly diagnose the issue. Some symptoms can be caused by other problems, like a bad oxygen sensor or ignition issues. 
• Underlying issues: Investigate why the converter failed in the first place. Issues like burning oil, engine misfires, or coolant leaks can cause a new converter to fail prematurely. 
• Cost: Be prepared for a high cost, as catalytic converters are expensive due to the precious metals they contain. This can be a significant expense, but the negative consequences of not replacing it are more costly in the long run.

Can you drive a Honda with a bad catalytic converter?

Running the car this way could reduce fuel efficiency and even damage some components. Rather than trying to drive a car with a missing catalytic converter, it's best to have it towed to a garage for repairs.

What is the life expectancy of a Honda catalytic converter?

Lifespan of a Catalytic Converter
Most catalytic converters eliminate more than 90% of an engine's harmful emissions. If your vehicle is kept in good working order, it can function well for more than 100,000 miles and sometimes as long as the vehicle is running and driving.
