A typical catalytic converter for a Honda Odyssey costs roughly $500–$1,800 for the part, with installed prices usually in the $800–$2,500 range depending on year, trim, and whether you choose OEM or aftermarket. Labor rates, local taxes, and emissions requirements can tilt the final price up or down.
Costs at a glance
Below is a practical breakdown showing common price ranges you’ll encounter when shopping for a Honda Odyssey catalytic converter. Prices vary by year, market, and the supplier’s policies, so use these as starting points when you request quotes.
- OEM Honda replacement (dealer or authorized shop): Part price typically about $600–$1,600; installed price often $1,200–$2,600, depending on labor rates and whether a single or dual-cat setup is involved.
- Aftermarket direct-fit catalytic converters (brand-name options like Walker, Bosal, MagnaFlow): Part price roughly $350–$1,200; installed price commonly $700–$1,900.
- Aftermarket universal catalytic converters (may require custom fabrication or welding): Part price around $100–$300; installed price commonly $400–$1,200, but total can rise if extensive exhaust work is needed.
Overall, most Odyssey owners see installed costs in the hundreds to a few thousand dollars, with OEM parts and California-compliant units tending to be on the higher end of the spectrum.
What affects the price
Several factors determine the final price of a catalytic converter replacement for a Honda Odyssey. Understanding these can help you compare quotes and avoid surprises.
- Parts type: OEM direct-fit vs aftermarket direct-fit vs universal catalytic converters. OEM parts are typically pricier but may offer guaranteed compatibility and warranty.
- Model year and engine configuration: Different generations of the Odyssey may use different catalytic setups (single vs multiple cats), which affects part price and installation complexity.
- California CARB status: In CARB states, you need CARB-approved converters, which can carry higher price due to certification and limited supply.
- Labor rates and shop location: Urban areas and high-cost markets tend to charge more for labor; some shops bill by the hour and can add costs for labor-intensive installations.
- Additional components or issues: Faulty O2 sensors, exhaust hangers, clamps, or related exhaust components may need replacement during the same service, adding to the total.
When you get quotes, ask if the price includes related parts (gaskets, sensors, clamps) and whether the unit is CARB-compliant in your state.
Shop smart: how to save and compare
To maximize value and avoid unnecessary costs, follow these practical steps before committing to a replacement.
- Get a diagnostic to confirm catalytic converter failure and rule out faulty sensors or wiring that can mimic a cat failure.
- Obtain multiple, itemized quotes (parts and labor) from independent shops and a Honda dealership for comparison.
- Ask for CARB-compliant options if you’re in a CARB-regulated state; request OEM or reputable aftermarket direct-fit parts with warranty.
- Verify the quoted installation time and whether any ancillary services (sensor replacement, exhaust work) are included.
- Check warranties on both the part and the labor, and inquire about core return policies if applicable.
Armed with quotes and a clear understanding of the options, you can choose a replacement that fits your budget while maintaining proper emissions performance.
Summary
The price for a Honda Odyssey catalytic converter varies widely based on part type (OEM vs aftermarket vs universal), year and engine configuration, and regional requirements. Expect part costs from a few hundred to over a thousand dollars, with installed totals commonly ranging from about $800 to $2,500 or more depending on the specifics. Always compare multiple, itemized quotes, confirm CARB compliance where required, and consider the total value of OEM compatibility, warranty, and labor when deciding what to buy.
