A typical installed price ranges from about $500 to $2,500, depending on parts and labor. Aftermarket parts are generally cheaper than Honda OEM parts, and having one or more converters, plus regional labor rates, can push the total higher.
Costs vary by model year and engine configuration, and can include sensors, gaskets, and labor time. Shop around for quotes, and ask for itemized estimates to understand what you’re paying for and whether sensors or additional repairs are required.
What drives the price of a catalytic converter replacement on a Honda Odyssey
Several factors influence the total bill. The most significant include the part type, the number of converters, and local labor rates.
OEM vs aftermarket parts
Choosing either OEM Honda parts or aftermarket equivalents is a major determinant of price and warranty coverage.
- OEM parts typically cost more but come with Honda’s warranty and guaranteed compatibility.
- Aftermarket direct-fit converters are usually cheaper and may come with their own warranties.
- Some aftermarket options may not meet emissions requirements for certain model years; confirm compatibility with your vehicle.
When deciding, balance price against warranty, expected lifespan, and whether the shop guarantees emissions compliance.
Number of converters and accessibility
The number of converters and how easily they can be replaced affect labor time and overall cost.
- Most Honda Odysseys have one catalytic converter, but some engines include a front pre-cat and a main catalytic converter.
- Two-converter jobs generally require more labor and higher parts costs than a single-converter repair.
Access to the exhaust system and any rust or corrosion can further increase labor time and pricing.
Typical price ranges for a Honda Odyssey catalytic converter replacement
Prices vary by model year, engine configuration, and whether you choose OEM or aftermarket parts. Here are ballpark installed ranges to help you plan:
- One catalytic converter (common scenario): aftermarket installed about $500–$1,100; OEM installed about $1,000–$2,400
- Two catalytic converters (less common, depending on the engine): aftermarket installed about $1,000–$2,000; OEM installed about $1,800–$3,500
- Dealership or high-cost-region pricing: generally at the upper end of these ranges and sometimes higher for OEM parts
Note: These figures typically include parts, labor, and standard exhaust gaskets or sensors. If oxygen sensors or additional components need replacement, or if the exhaust system is heavily corroded, the final price can rise. Always request an itemized estimate that specifies parts, labor, sensors, and accessories included.
Ways to save on catalytic converter replacement
To keep costs down, consider comparing quotes from independent shops, asking for aftermarket parts when appropriate, and checking whether sensors or gaskets are included in the estimate.
Also, confirm whether the price covers both parts and labor, and whether any required emissions testing or inspections are included in the service.
Summary
For a Honda Odyssey, expect roughly $500 to $2,500 for a single catalytic converter replacement, with higher costs if there are two converters, if OEM parts are chosen, or if labor rates are high. Shop around, compare OEM vs aftermarket options, and ensure you receive a clear, itemized estimate that includes all necessary components.

Do Honda Odysseys have catalytic converter problems?
A common reason for the check engine light in a 2005-2011 Honda Odyssey is a failing catalytic converter. The most frequent codes you'll see are P0420 and P0430, which mean the converter's efficiency is below the required threshold.
Is it cheaper to fix or replace a catalytic converter?
The cheapest way to fix a bad catalytic converter is generally to have an auto mechanic weld in a new universal model. That could cost between $200 to $300, but your catalytic converter replacement cost could be higher if your vehicle requires a direct-fit catalytic converter.
