Costs typically range from about $500 to $2,500 to replace catalytic converters on a 2007 Honda Odyssey, depending on whether you replace one or both units, and whether you choose OEM or aftermarket parts.
On a 2007 Odyssey with a 3.5-liter V6, there are two catalytic converters (one on each bank). Replacing only the failed unit is cheaper, but some cars need both replaced if they’re deteriorated or damaged. OEM Honda converters cost more but guarantee exact fit and sensor compatibility; aftermarket direct-fit options are cheaper but vary in quality. Labor rates and regional costs also contribute to the total.
What affects the price
The following factors most influence the total bill for replacing a catalytic converter on a 2007 Honda Odyssey.
- Number of catalytic converters to replace: single-cat vs dual-cat setups. The Odyssey’s dual-cat configuration means costs can double if both need replacement.
- Parts type: OEM direct-fit vs aftermarket equivalents. OEM parts are typically more expensive but offer factory fit and warranty; aftermarket parts are cheaper but quality can vary.
- Labor rate and time: shop hourly rates and the time required to remove the old converter(s), deal with any rusted fasteners, and reinstall the exhaust system. Longer jobs raise labor costs.
- Additional components: gaskets, O2 sensors, heat shields, and mounting hardware may need replacement, adding to both parts and labor.
Concluding: In practice, the final price reflects a combination of how many converters are replaced, the choice of parts, and the labor environment where the work is done.
Typical cost ranges for a 2007 Honda Odyssey
Prices can be broken down into scenarios to give a clearer budgeting picture. The ranges below assume the vehicle has two catalytic converters and is repaired at a typical shop.
- One catalytic converter replaced (aftermarket parts): Parts roughly $200–$500; labor about $100–$300; total estimate $300–$800.
- One catalytic converter replaced (OEM parts): Parts roughly $500–$1,000; labor about $150–$350; total estimate $650–$1,350.
- Two catalytic converters replaced (both sides, aftermarket parts): Parts roughly $400–$1,000; labor about $250–$600; total estimate $650–$1,600.
- Two catalytic converters replaced (both sides, OEM parts): Parts roughly $1,000–$2,000; labor about $400–$900; total estimate $1,400–$2,900.
Note: If theft has occurred or sensors were damaged, you may see additional costs for sensors, wiring, or more extensive exhaust work. Prices vary by region and shop rates.
Ways to save money and alternatives
Smart budgeting can help you minimize costs while keeping safety and emissions compliance intact. Consider these strategies as you evaluate replacement options.
- Get multiple quotes from independent shops and dealers to compare price and warranty.
- Ask about aftermarket direct-fit converters that meet OEM specs to balance price with reliability.
- Request a diagnostic to confirm which cat(s) are failing before approving replacement.
- Check whether some shops offer bundled pricing or discounts for replacing more parts at once (e.g., exhaust system service).
Concluding: A careful, informed shopping approach can save several hundred dollars and help ensure you get a warranty-backed fix that lasts.
Summary
Replacing a catalytic converter on a 2007 Honda Odyssey typically costs between roughly $300 and $2,900 depending on whether you replace one or both converters, and whether you use aftermarket or OEM parts, plus labor. Start by diagnosing which converter(s) need replacement, compare multiple quotes, and weigh OEM versus aftermarket options to balance cost and reliability. Always confirm warranties and compatibility with sensors and emissions systems.
