The typical installed price for a single catalytic converter on a Prius ranges from about $900 to $2,500, with OEM parts usually at the higher end; if your model uses two converters or if theft or extensive damage is involved, costs can climb toward $2,000 to $5,000.
What factors influence the price
Several variables determine how much you’ll pay to replace a catalytic converter on a Prius, including how many converters need replacement, whether you choose aftermarket or OEM parts, your Prius model year, labor rates in your area, and whether any related components (such as sensors) must be replaced or reprogrammed.
Model year and exhaust configuration
Most Prius generations use at least one catalytic converter, and many models have two in the exhaust sequence (a pre-cat near the engine and a main cat downstream). The exact arrangement affects both parts cost and labor time.
Parts choice: aftermarket vs OEM
Aftermarket catalytic converters are typically cheaper but must be carefully matched to your vehicle to avoid emissions or performance issues. OEM (Toyota) converters cost more but are designed to fit and function exactly as the factory intended and may be warranted longer.
Labor and regional pricing
Labor rates vary by shop and region, and replacement time can depend on access to the converter(s) and the need to remove other components. Typical jobs take 1–3 hours, but complications can extend that time.
Typical price ranges
Below are installed price ranges you’re likely to encounter. The figures assume standard service and do not include added repairs or diagnostics.
- One aftermarket catalytic converter (installed): $350–$900
- One OEM Toyota catalytic converter (installed): $1,000–$2,400
- Two aftermarket catalytic converters (installed): $1,200–$3,200
- Two OEM catalytic converters (installed): $2,000–$5,000
Prices vary by model year, whether the vehicle has one or two converters, and local shop rates. If theft repair is involved, or if extra components (like sensors) must be replaced, expect the higher end of the range.
Other costs and considerations
In addition to the converter itself and labor, you may encounter diagnostic fees, disposal fees, and potential sensor replacements. Some vehicles require reprogramming or recalibration of the engine control unit after replacement, which can add to the cost. If your car is still under an emissions warranty, parts of the replacement may be covered depending on your location and the exact warranty terms.
How to get an accurate quote
To ensure you’re getting a fair price, obtain multiple itemized quotes from reputable shops. An itemized estimate should break out parts, labor, taxes, disposal, and any additional services (like sensor replacement or reprogramming).
- Have your vehicle’s VIN, model year, and exact symptoms ready when requesting quotes.
- Ask for a price that includes parts (with part numbers if possible) and labor, plus any guarantee or warranty on the parts and workmanship.
- Request that the quote specify whether an OEM or aftermarket converter is being used and whether any sensors or related components will be replaced.
Note that quotes can change if the shop discovers additional issues, such as damaged exhaust mounts, rusted bolts, or failing oxygen sensors. It’s prudent to get a second opinion if a price seems unusually high or low.
Tips to save money
Consider the following to reduce costs without compromising safety or emissions compliance:
- Compare several reputable shops and request written estimates.
- Ask about aftermarket converters with a strong warranty from a known manufacturer.
- Inquire whether the quote includes all related components (sensors, gaskets, clamps) and any required reprogramming.
- Check if your vehicle’s emissions warranty covers the converter or related parts.
- Verify whether the repair is needed immediately or if a temporary fix (if safe) is acceptable while you shop for a better price.
Having a clear plan and comparing multiple quotes can help you balance cost with reliability and emissions compliance.
Warranty and protection notes
Many catalytic converters are covered by an emissions warranty in the United States (commonly 8 years / 80,000 miles for major emissions components; terms vary by state and vehicle). If a failure is covered, your replacement may be partially or fully paid by the manufacturer or dealer, depending on age, mileage, and location. Check your state’s requirements and your vehicle’s warranty documentation for specifics.
Summary
Replacing a catalytic converter on a Prius is a substantial service, with costs heavily influenced by the number of converters, part choice, and labor. Plan for roughly $900 to $2,500 for a single converter, and potentially $2,000 to $5,000 if two converters are involved or if OEM parts are used. Get multiple, itemized quotes, and consider warranty coverage when deciding between aftermarket and OEM parts. If you suspect an emissions-related issue, address it promptly to avoid further damage or failures on inspection.
