In short, replacing a catalytic converter on a Honda typically runs from a few hundred dollars for an aftermarket part installed by a savvy DIYer or a budget shop to several thousand dollars for OEM parts at a dealer. The total price hinges on the model, whether there’s one or more converters, and the labor rate in your area.
What affects the price
Several factors determine the total cost when replacing a catalytic converter on a Honda.
Parts options
Costs vary by part type and whether you choose OEM or aftermarket, as well as whether your model uses a single catalytic converter or multiple converters.
- Aftermarket direct-fit or universal catalytic converters: Part prices commonly range from about $120 to $600 for many Honda applications, with direct-fit units typically at the higher end of that range.
- OEM Honda catalytic converters: Part prices generally run from roughly $600 to $1,800, though some newer or higher-performance models can be higher.
- Used or remanufactured converters: Part prices can be as low as about $100 to $500, though reliability and compatibility risks apply.
The part choice has a big impact on total cost, especially on models with two converters or complex exhaust routes.
Labor costs and installation
Labor adds another major factor. Prices vary by region and shop type, and installation time depends on accessibility and whether one or two converters are involved.
- Labor rates: Independent repair shops typically charge about $75 to $120 per hour; dealerships often range from $100 to $150 per hour.
- Installation time: Replacing one converter generally takes 1 to 3 hours; more time may be required for two converters or difficult-to-access layouts.
- Total installed price (rough ranges): Aftermarket parts plus labor commonly total around $300 to $1,100; OEM parts plus labor commonly total around $800 to $2,300; using a used converter plus labor can bring total in the low $300s to about $1,000.
Always get a written estimate that itemizes parts and labor, and check whether local emissions regulations require using OEM parts in certain cases.
Important considerations for Honda owners
Warranty and emissions rules
In the United States, components like catalytic converters fall under emissions warranties and are often covered for a certain number of years or miles. Federal rules typically provide substantial coverage, while California and other states may have longer protections. Replacing the converter with non-OEM parts may affect warranty eligibility for some vehicles; always verify your vehicle's warranty status and local regulations before proceeding.
Shop choice and where to buy
Options include a Honda dealership, independent auto repair shops, or online parts retailers. Dealers tend to offer OEM parts and may be more expensive; independent shops often offer lower labor rates and more flexible scheduling. If you’re shopping for used parts, ensure they’re in good condition and compatible with your VIN.
Summary
Replacing a catalytic converter on a Honda is not a one-size-fits-all cost. The exact price depends on the model and engine layout, the choice between OEM and aftermarket parts, whether you have one or two converters, and labor costs in your area. Plan for roughly $300 to $2,500 in typical installed costs, with higher-end models and twin-converter setups at the top end. Always obtain a written estimate, compare options, and confirm any emissions warranty implications before proceeding.
