Most Toyota Corolla catalytic converter replacements cost roughly $800 to $1,600 installed, with OEM dealer parts at the higher end and aftermarket parts at the lower end.
The exact price depends on the year and engine of your Corolla, whether one or two catalytic converters are involved, the type of parts you choose (OEM versus aftermarket), your local labor rates, and any additional exhaust or warranty considerations.
What affects the cost
Below are common options and their typical price ranges to help you budget for the replacement.
- OEM Toyota catalytic converter (dealer direct-fit): Typical installed price range is about $1,100 to $2,000, depending on the exact part and labor needs.
- Aftermarket direct-fit catalytic converter (non-OEM): Typical installed price range is about $800 to $1,400, depending on brand and quality, plus labor.
- Premium or dual-cat configurations (if your model has more than one converter): Typical installed price range is about $1,600 to $3,000, depending on parts and labor requirements.
Prices vary by model year and region; always request a detailed breakdown of parts and labor when comparing quotes.
Labor and installation considerations
Labor time for a catalytic converter replacement is typically 1–3 hours, depending on access and whether the vehicle has one or two converters; labor rates vary by shop and region.
- Average labor time: 1–2 hours for a straightforward, single-cat replacement; 2–3 hours or more if access is difficult or there are two converters.
- Labor rate ranges: $75–$125 per hour at many independent shops; $100–$200 per hour at dealers or in high-cost metro areas.
Ask for a clear line-item quote that separates parts and labor, and confirms whether the price includes any gaskets, seals, or core charges.
How to get an accurate quote
Before you visit a shop, gather information about your vehicle and your preferences for parts to ensure you receive apples-to-apples estimates.
- Identify whether your Corolla has one catalytic converter or a second cat in the exhaust (some configurations do).
- Decide between OEM Toyota parts and aftermarket direct-fit alternatives, noting any warranty preferences.
- Request a detailed quote that lists part price, labor hours, hourly rate, and any additional fees (core charges, disposal, or shop supplies).
- Get multiple quotes from independent shops and a dealer service department to compare prices and warranties.
- Ask about warranties on the new converter and on the labor, and whether the quote includes any required inspections or diagnostic fees.
Collecting several estimates helps you gauge market pricing, avoid surprise fees, and choose a solution that fits your budget and needs.
Summary
In most cases, you’ll pay roughly $800 to $1,600 installed for a Toyota Corolla catalytic converter with aftermarket parts, and about $1,100 to $2,000 or more with OEM dealer parts, depending on whether one or two converters are involved and how the shop prices parts and labor. Prices vary by model year, engine type, region, and labor rates, so always obtain multiple detailed quotes and verify warranty terms before proceeding.
