On average, replacing the catalytic converter on a Honda Odyssey costs roughly $800 to $3,500, depending on whether you replace one or both converters and whether you choose aftermarket or OEM parts.
In this article, we break down the cost drivers, offer typical price ranges for single- and dual-converter replacements, and provide tips for getting accurate estimates from repair shops.
What drives the cost
Several factors influence the final bill when replacing a catalytic converter on a Honda Odyssey.
- Number of converters involved: single-cat versus both banks (many Odyssey models use two catalytic converters).
- Parts choice: aftermarket (often cheaper) versus OEM/dealer parts (more expensive but guaranteed fit and warranty).
- Labor rates and time: shop location, local wage levels, and how easy the cat is to access.
- Additional components: oxygen sensors, gaskets, mounting hardware, and possible replacement of downstream pipes.
- Vehicle year and engine configuration: newer or differently arranged models may affect fitment and labor time.
Understanding these factors helps you interpret estimates and compare quotes from different shops.
Typical price ranges for a Honda Odyssey
Prices vary by scenario (single-cat versus two-cat) and parts choice. The ranges below reflect common quotes from U.S. repair shops as of 2024–2026.

- Two catalytic converters replacement (both cats) – OEM parts and labor: roughly $2,250–$4,600
Conclusion: Replacing both catalytic converters on a Honda Odyssey typically ranges from about $1,200 to $4,600, influenced by parts and labor costs.
Tips to save money and get an accurate quote
Before you commit, consider these practices to ensure you’re getting a fair price and a complete job.
- Get multiple written quotes from reputable shops and ask them to itemize parts and labor.
- Ask whether the estimate includes labor, taxes, and any disposal or shop fees.
- Inquire about whether oxygen sensors or other related components might need replacement or inspection.
- Consider both aftermarket and OEM options, and verify fitment for your specific Odyssey model year and engine.
- Check reviews and ask specifically about warranty on the new catalytic converters.
Bottom line: A clear, itemized estimate and comparisons across shops help prevent surprises and ensure you’re paying for the appropriate scope of work.
Summary
The cost to replace a catalytic converter on a Honda Odyssey varies widely. A single-cat replacement typically falls in the $600–$2,350 range, while replacing both converters commonly runs $1,200–$4,600, with OEM parts at the higher end. Factors such as part type, labor rate, model year, and whether additional components are needed drive the final price. To get the best value, obtain multiple, detailed quotes and verify exactly what is included in each estimate.
