Replacing a catalytic converter typically costs about $1,000 to $3,000 in the United States, depending on whether you choose aftermarket or OEM parts and on your vehicle. If the catalytic converter is integrated with or located near the exhaust manifold, the price can rise to roughly $2,000 to $4,500 or more. This article breaks down the factors, price ranges, and ways to save on the repair.
What affects the price
Several factors influence the final bill for catalytic converter and exhaust manifold work, including the type of part, the vehicle make and model, the number of converters, the complexity of access, regional labor rates, and whether any sensors or related components must be replaced at the same time. The more expensive OEM parts or dual-cat setups, the higher the overall cost. Labor costs can swing based on shop location and technician experience.
Cost ranges for standalone catalytic converter replacements
The following ranges reflect typical prices for replacing a catalytic converter on a wide range of passenger vehicles in the United States, as of 2024–2025. Actual prices depend on your car and where you live. The list below separates scenarios to help you estimate what your job might cost.
- Standalone aftermarket catalytic converter (direct-fit): Parts roughly $300–$700; labor about 1–2 hours; total approximately $600–$1,900.
- OEM catalytic converter (direct-fit, manufacturer-approved): Parts roughly $800–$2,000; labor about 1–3 hours; total approximately $1,000–$3,500.
- Vehicles with two catalytic converters (dual-cat setups): If both converters require replacement, total price can be $1,200–$4,000 or more, depending on parts and labor for each unit.
Overall, standalone catalytic converter replacements commonly fall in the $600–$3,500 range, with higher-end vehicles or dual-cat configurations pushing toward the upper end of that spectrum.
Costs when the catalytic converter is integrated with the exhaust manifold
In some vehicles, the catalytic converter is built into the exhaust manifold or sits very close to it, which changes the replacement dynamic and price. This configuration often requires more expensive parts and longer labor times.
- Cat-in-manifold replacement (catalytic converter integrated with the manifold): Parts roughly $1,000–$2,500; labor about 3–6 hours; total approximately $2,000–$5,500.
- Exhaust manifold replacement without replacing the catalytic converter (or with separate parts): Parts roughly $150–$500; labor about 2–5 hours; total approximately $500–$1,800.
For vehicles with a cat-integrated manifold, the job tends to be more expensive due to the specialized part and potentially more extensive labor. Always obtain a written estimate that itemizes parts and labor to compare options.
What to expect at the shop
When you bring your car in, a shop will typically diagnose emissions-related symptoms, inspect the catalytic converter and exhaust system, and verify sensor function. Expect a diagnostic charge in some shops, often offset if you proceed with the repair. Quotes should itemize parts (aftermarket vs OEM, number of converters) and labor time, and they should note any ancillary costs such as gaskets, sensors, or alignment checks. If multiple issues exist (for example, a failing oxygen sensor or exhaust leaks), these can add to the total.
Cost-saving tips
To help manage costs, consider the following strategies. Get multiple quotes, verify that parts are appropriate for your vehicle and emission standards, and ask about warranties on parts and labor. If your car is out of warranty, compare aftermarket parts against OEM options for a balance of cost and performance. In some cases, a repair may be prevented with minor fixes or sensor replacements that trigger the diagnostic codes.
Summary
In most cases, replacing a catalytic converter without the manifold is generally in the $600–$3,500 range, depending on part choice and labor. If the converter is integrated with the exhaust manifold, prices tend to be higher, typically in the $2,000–$5,500 range, due to more complex parts and longer labor. Prices vary by vehicle type, region, and shop, so secure written estimates and weigh OEM versus aftermarket options. Regular maintenance and prompt attention to emissions issues can help minimize the risk of more expensive repairs later.
