The typical replacement cost for a 2011 Honda Odyssey catalytic converter ranges from about $150–$450 per converter for aftermarket parts, and $700–$1,800 per converter for OEM Honda parts, plus roughly $100–$300 in labor per converter.
Because the Odyssey's exhaust system often has two catalysts (front and rear), the total bill can vary widely depending on which unit is being replaced, whether you choose OEM or aftermarket parts, and local labor rates. This article breaks down the pricing landscape and what to expect when shopping for a replacement.
What you’re buying
Before listing prices, it helps to understand the parts involved and why costs differ. The 2011 Odyssey can have two catalytic converters located at different points in the exhaust system. You may need one or both, depending on failure diagnosis and emissions requirements. Prices vary by supplier, whether you choose OEM or aftermarket, and whether the unit is front- or rear-facing.
- OEM direct replacement: Genuine Honda parts designed to match the original equipment, typically the most expensive option.
- Aftermarket direct-fit: Third-party converters built to fit your vehicle exactly, usually cheaper than OEM but must meet emissions standards.
- Remanufactured or universal converters: Often the lowest upfront price, but may require extra fitment work and come with variable warranties.
- State regulations: In some states (and especially California), CARB-compliant units are required for street-legal replacement.
Understanding these categories helps you compare apples to apples and anticipate total costs beyond the part price.
Price ranges by source
- OEM direct replacement (Honda): roughly $700–$1,800 per converter, depending on whether it's the front or rear unit.
- Aftermarket direct-fit: roughly $150–$450 per converter, with some premium brands up to about $600.
- Remanufactured or universal converters: often $100–$350, but may require additional parts, fitment checks, and warranty considerations.
Labor adds to the parts cost. Typical shop labor for replacing one converter runs about $100–$300, depending on access and local rates. If both converters need replacement, you’ll multiply these figures accordingly and may incur extra costs for gaskets, sensors, or exhaust clamps.
How to shop and save
Smart shopping can lower the overall bill without sacrificing safety or emissions compliance. Here are practical steps to compare quotes and avoid surprises.
- Get multiple quotes for parts and labor, and ask for itemized estimates that separate parts, labor, and any fees.
- Confirm CARB compliance if you’re in a state that requires it for street-legal replacements.
- Ask about warranties on the catalytic converter and any remanufactured units, and whether the warranty covers both parts and labor.
- Consider whether replacing one converter now and the other later is possible based on diagnosis and fuel-economy impacts.
By comparing options and understanding the trade-offs between OEM, aftermarket, and remanufactured units, you can choose a solution that meets your budget and emissions requirements.
Summary
For a 2011 Honda Odyssey, expect about $150–$450 per converter for aftermarket direct-fit parts or $700–$1,800 per converter for OEM Honda parts, with roughly $100–$300 in labor per converter. Most Odysseys use two converters (front and rear), so total costs can range from a few hundred to several thousand dollars depending on part choice, number replaced, and local labor rates. Always verify emissions compliance and obtain several quotes to ensure you get a fair price and solid warranty.
