How much does it cost to replace a catalytic converter on a Ford Flex?
Replacing a catalytic converter on a Ford Flex typically costs from roughly $900 to $2,000 for a single converter, and $1,800 to $4,000 if your vehicle requires both converters. Actual prices depend on parts choices, labor rates, and how many converters need replacement.
To understand the question in depth, the price is influenced by whether you choose an aftermarket or OEM part, how many catalytic converters your Flex uses, labor time and regional shop rates, and whether related components (like oxygen sensors or exhaust gaskets) must also be replaced during the job. The Ford Flex, produced from 2009 through 2019, commonly uses a V6 engine configuration that can involve more than one catalytic converter, which affects the total cost.
What drives the price
Prices for catalytic converter replacement are shaped by several factors. The following elements help determine the final bill:
- Parts choice: aftermarket converters are usually cheaper than OEM Ford parts, but quality and warranty vary.
- Labor costs: shops charge hourly rates that vary by region; more hours mean a higher total.
- Number of converters: if your Flex needs one converter, it costs less than replacing both.
- Vehicle access and complexity: some years/models are easier to service; tougher layouts can raise labor time.
- Additional components: oxygen sensors, gaskets, clamps, and mounting hardware may need replacement.
Given these variables, the best approach is to obtain multiple written price quotes from reputable shops that itemize parts and labor.
Single catalytic converter replacement
Below are typical installed cost ranges for replacing just one catalytic converter on a Ford Flex, depending on the parts you choose.
- Aftermarket single-cat replacement: Parts $200–$700; labor $150–$400; total $350–$1,100.
- OEM Ford single-cat replacement: Parts $600–$1,300; labor $150–$450; total $750–$1,750.
Prices can vary by year, model specifics, and shop, so it’s wise to shop around and request quotes that include both parts and labor.
Two catalytic converters on a Ford Flex
If your Flex requires the replacement of both catalytic converters, the cost will be higher, with a similar split between aftermarket and OEM parts.
- Two aftermarket converters: Parts $400–$1,000; labor 2–4 hours; total $700–$2,000.
- Two OEM Ford converters: Parts $1,000–$2,000; labor 2–4 hours; total $1,800–$4,000.
Again, exact pricing depends on your vehicle’s year and configuration, plus any sensor or gasket replacements that may be required during the job.
Saving money and getting a good deal
Smart shopping can help you trim costs without compromising reliability. Consider these strategies before authorizing work:
- Get multiple written estimates from independent repair shops and dealership service departments.
- Ask about warranties on both parts and labor, and whether remanufactured or refurbished converters are an option.
- Clarify if oxygen sensors or other components are included in the quote or billed separately.
- Check if your vehicle is still under any applicable factory or extended warranty that could cover part of the repair.
- Consider timing and promotions; some shops run discounts or bundled exhaust service deals.
Remember to avoid cuts that could compromise emissions performance or warranty considerations. A reputable shop will explain the trade-offs between parts quality, longevity, and price.
What to expect at the shop
When you bring your Ford Flex in for catalytic converter work, expect a diagnostic assessment to confirm the failure and identify related issues. The process typically involves removing the faulty converter(s), installing the replacement unit with new gaskets and clamps, possibly replacing affected oxygen sensors, and testing the exhaust system for leaks and proper operation. Labor times vary with the vehicle’s year, model, and the complexity of access.
Diagnostic fees may apply if you’re not already under evaluation for the issue, and some shops roll diagnostics into the overall repair price if you proceed with the replacement.
Summary
For a Ford Flex, budget roughly $900–$2,000 to replace a single catalytic converter, and $1,800–$4,000 if both converters are needed. Prices depend on OEM versus aftermarket parts, labor rates, the number of converters, and any additional components touched during the repair. To secure the best value, obtain several written quotes, confirm warranties, and ensure the selected parts meet emissions standards for your year and model.

Is it worth replacing a catalytic converter?
Yes, replacing a catalytic converter is often worth it to avoid legal penalties, significant engine damage, and poor performance. While the initial cost is high, driving without one is not recommended due to the risk of failing emissions tests, a loud engine, reduced fuel efficiency, and potential damage to other engine components.
Reasons to replace your catalytic converter
This video explains the reasons why replacing a catalytic converter is worth it: 49sStudent LessonYouTube · Sep 18, 2023
- Avoid legal and inspection issues: Many states require a working catalytic converter to pass emissions and smog tests for vehicle registration. Driving without one is illegal in most places.
- Prevent engine damage: A malfunctioning or clogged converter can cause the engine to work harder, leading to sluggishness, misfires, and other issues. Continued driving can lead to more extensive and costly engine damage or failure.
- Improve vehicle performance: A new converter will restore engine performance, improve acceleration, and can prevent other problems like stalling.
- Increase fuel efficiency: A clogged converter can decrease your gas mileage, so replacement can improve your fuel economy.
- Reduce harmful emissions: The primary function of a catalytic converter is to reduce harmful pollutants from your vehicle's exhaust, which is beneficial for the environment.
When to consider replacement
- Signs of a problem: Look for symptoms like reduced engine power, a sulfur or rotten egg smell from the exhaust, poor acceleration, or a loud rattling noise from the exhaust system. The "check engine" light is often a sign of a failing catalytic converter, but it could also be triggered by other engine issues, so a proper diagnosis is important.
- Cost vs. long-term cost: Even though replacement is expensive, the cost of ignoring the problem can lead to even more expensive engine repairs down the line.
- Repair vs. replacement: If the catalytic converter is damaged, get an estimate for both repair and replacement. Often, replacement is the better option if the repair cost is similar to a new part.
What is the cheapest way to replace a catalytic converter?
The cheapest way to fix a catalytic converter is to have a universal converter welded in by a muffler shop, which can cost between $200$ 200$200 and $300$ 300$300. For certain issues, a less expensive alternative to replacement could be a catalytic converter cleaner or, for certain code issues, an oxygen (O2) sensor spacer, but a replacement is the only guaranteed solution for a clogged converter.

Less expensive repair options
- Universal converter replacement: A universal converter is a cheaper alternative to a direct-fit replacement. A muffler shop can cut out the old converter and weld in the new universal one, which can cost anywhere from $200$ 200$200 to $300$ 300$300.
- Catalytic converter cleaner: If the converter is simply clogged with soot from a rich fuel mixture, a chemical cleaner may be effective. However, this is not a guaranteed fix and may only be a temporary solution.
- Oxygen sensor spacer: In some cases, a P0420 or P0430 code might be a false positive caused by an oxygen sensor issue. A cheaper fix can be to install an O2 sensor spacer, which can be made from a "spark plug non-fouler" or purchased online. However, this is only a temporary solution and may not work, and it may not be legal for emissions testing.
Other factors to consider
- Diagnosis is key: Before choosing a repair option, make sure to properly diagnose the issue. An O2 sensor issue or exhaust leak might be the problem, and addressing that first could save you money.
- Direct-fit vs. universal: If your vehicle requires a direct-fit converter (e.g., newer cars where it's part of the exhaust manifold), it will likely be much more expensive, ranging from $300$ 300$300 to $2,500$ 2 comma 500$2,500 or more for just the part.
- DIY installation: If you are comfortable with auto repairs, you could potentially save on labor costs by replacing the converter yourself, especially if you have a universal fit model that you can bolt or clamp into place.
