The installed cost typically ranges from about $900 to $2,500, depending on whether one or both catalytic converters are replaced and whether you choose OEM or aftermarket parts. The 2005 Odyssey often has two catalytic converters, which can affect the total price.
In this report, we break down the factors that influence price, outline common cost scenarios for the 2005 Odyssey, and offer tips to save money while ensuring the repair meets emissions standards. Prices can vary by region, shop, and the exact setup of your vehicle.
What drives the price
The total cost is driven by how many converters are replaced, the type of parts used, the labor rate, and any related components that must be replaced during the job.
- Number of catalytic converters affected (one vs. two) and the accessibility of the exhaust system
- Part type: OEM (dealer) replacement versus aftermarket direct-fit or universal converters
- Labor rate and hours required to remove old parts and install new ones
- Vehicle condition and need to replace related components (gaskets, bolts, O2 sensors)
- Shop type and location (independent shop vs. dealership; regional price differences)
Prices vary widely by region and shop, so getting several quotes is recommended to gauge a fair price.
Typical cost scenarios
Below are rough installed cost ranges for common cases on a 2005 Honda Odyssey. Variations depend on your vehicle’s exact setup and local labor rates.
Single catalytic converter replacement (aftermarket parts)
One converter replaced with aftermarket parts: typically $300 to $750 installed.
- Notes: Lower end reflects aftermarket direct-fit parts with moderate labor; genuine OEM parts would be higher.
Expect potential additional costs if sensors or gaskets need replacement during the job.
Single catalytic converter replacement (OEM parts)
One converter replaced with OEM parts: typically $650 to $1,350 installed.
- Notes: OEM parts cost more, but some owners prefer exact-fit specs and warranty coverage.
Labor and incidental hardware may still influence the final price, and some shops charge diagnostic fees if a screen shows codes.
Two catalytic converters replaced (aftermarket parts)
Both converters replaced with aftermarket parts: typically $700 to $1,800 installed.
- Notes: Parts are cheaper than OEM, but total price rises with two units plus labor.
Additional components such as sensors or gaskets can add modest costs to the job.
Two catalytic converters replaced (OEM parts)
Both converters replaced with OEM parts: typically $1,400 to $3,000 installed.
- Notes: Highest end of the range reflects OEM pricing and dealership labor rates.
With two cats, ensure you verify that the replacement meets your state’s emissions requirements and includes the proper warranties.
Cost-saving tips and considerations
To manage costs without sacrificing emissions compliance or reliability, consider these approaches.
Smart shopping strategies
- Get multiple quotes from independent shops and Honda dealers to compare labor rates and parts pricing
- Ask for itemized estimates that separate parts, labor, and diagnostic fees; request part numbers to distinguish OEM from aftermarket
- Consider reputable aftermarket converters that meet EPA or state standards and come with a warranty
- Look for promotions, coupons, or bundled services from local shops
Note that choosing very low-cost options or skipping related replacements (like sensors or gaskets) can lead to future problems or failed emissions tests.
Summary
Replacing a catalytic converter on a 2005 Honda Odyssey is a mid-to-high-cost repair, influenced by how many converters are replaced, the part type, and local labor rates. Expect installed prices ranging from a few hundred dollars for a single aftermarket converter to several thousand dollars for OEM two-cat replacements. Obtain multiple quotes, verify part compatibility with emissions standards, and weigh the benefits of OEM versus aftermarket parts.
