Prices vary, but for a 2006 Honda Odyssey you should expect roughly $200-$900 per catalytic converter. The Odyssey typically uses two converters, so parts for both commonly total $400-$1,800, with labor adding about $100-$400 per converter depending on shop and location.
Parts options and typical price ranges
There are several routes to replacement, each with different price points and fitment considerations. The main choices are OEM direct-fit units, aftermarket direct-fit units, and universal or aftermarket options that require modification.
OEM direct-fit catalytic converters
OEM units are made by Honda or its suppliers and designed to match factory fitment and emissions performance. Prices are typically higher but come with factory warranty and guaranteed compatibility.
- Per converter: typically $450–$900
- Two-converter (both upstream and downstream) sets: often $850–$1,800 for the parts alone
- Optional items sometimes included: gaskets and hardware, sometimes sold separately
Labor and additional parts will increase the total; expect installation to add roughly $100–$300 per converter, depending on vehicle access and shop rates.
Aftermarket direct-fit catalytic converters
Aftermarket direct-fit converters are designed to bolt in with fewer modifications and can offer substantial savings or better warranties depending on the brand. Quality and fit can vary, so check reviews and return policies.
- Per converter: typically $150–$600
- Two-converter set: often $300–$1,200
- Quality brands with warranties exist at the higher end of this range
Labor and potential sensor work can add about $100–$300 per converter, and some shops charge more for complicated exhaust routing or corrosion issues.
Universal catalytic converters
Universal converters are not vehicle-specific and require custom fitting, cutting, welding, and possibly additional exhaust components. While they can be cheaper upfront, they may not pass emissions tests in some areas and could require professional installation.
- Per unit: typically $100–$300
- Two-converter setups: $200–$600
Professional installation is strongly recommended; budget for additional labor and potential modification costs, and verify emission compliance in your state.
Labor considerations and installation tips
The exact labor cost depends on shop rates and the complexity of access to the exhaust system. Replacing both converters at once can save time and may qualify for a bundled labor rate.
Where to buy and what to expect
Possible sources include Honda dealerships, auto parts retailers, online marketplaces, and salvage yards. Compare prices, warranty terms, and core charges; shipping can affect total cost, especially for heavy catalytic converters.
- Honda dealership or official Honda parts: typically higher prices, but strongest warranty and compatibility assurances
- Major auto parts stores (AutoZone, Advance Auto Parts, O'Reilly): broad range, frequent sales, and available installation services
- Online retailers and marketplaces (RockAuto, Amazon, eBay): can be cheapest, but verify compatibility and return policies
- Used or salvaged converters from reputable yards: lowest price, but higher risk of wear and shorter remaining life
Plan ahead for core charges and shipping; some sellers require you to return your old converter to receive the full price back as a core credit.
Warranty and installation tips
OEM replacements typically come with a manufacturer warranty (often 1–3 years or 12,000–36,000 miles). Aftermarket parts may include limited warranties that vary by brand. Ensure the sensors (O2 sensors) and exhaust gaskets are replaced if needed, and have a professional install to avoid leaks or misalignment that can trigger check engine lights or failed emissions tests.
Summary
Replacing catalytic converters on a 2006 Honda Odyssey can be a sizable expense. Expect part prices ranging from about $150 to $900 per converter depending on OEM vs aftermarket, with labor typically $100–$300 per converter. Since this model often uses two catalysts, total outlay for parts and labor commonly ranges from roughly $600 to $2,400, though exact prices depend on your location, brand choices, and whether both units are replaced at once. Shopping around and comparing dealers, retailers, and warranties can help you find the best balance of cost and reliability.
