For a 2009 Honda Accord, a catalytic converter replacement generally falls in a broad range from a few hundred dollars to over a thousand dollars installed, depending on whether you choose an aftermarket or OEM part and how much labor is required. Here’s a current, practical guide to pricing, options, and what affects the final bill.
The question hinges on several factors: the engine type (2.4L four-cylinder vs. 3.5L V6), how many catalytic converters the exhaust system uses, and whether you buy a new OEM unit, a direct-fit aftermarket, a remanufactured or used part, plus the labor cost at the shop you choose. Prices can vary by region and by the shop’s labor rates, and metal prices can influence aftermarket part costs.
What affects the price
Prices are driven by part type, engine configuration, and installation complexity. The 2009 Accord could have different exhaust setups depending on the trim and engine, which affects how many converters you’ll replace and how they’re mounted. Here are the common buying options and what they typically cost, including estimated installation:
- OEM direct-fit catalytic converter (Honda-brand or dealer part): Part price typically $500–$900; installation often $150–$350; total installed around $650–$1,250 (regional variations apply).
- Aftermarket direct-fit catalytic converter (brand-name or budget): Part price typically $180–$550; installation $150–$300; total installed roughly $330–$850.
- Used catalytic converter from a salvage yard: Part price typically $70–$350; installation $150–$300; total installed roughly $220–$650.
- Remanufactured or rebuilt catalytic converter: Part price typically $200–$500; installation $150–$300; total installed roughly $350–$800.
Prices can vary based on which converter(s) your car requires, local labor rates, and whether additional exhaust-work is needed (such as replacing gaskets or repairing welded connections). Always confirm the exact part number and fit for your VIN before purchasing.
Shopping tips and considerations
OEM vs aftermarket
OEM parts are designed to match the original equipment in fit and performance, but they’re usually pricier. Aftermarket direct-fit converters are typically more affordable and widely available, though quality can vary by brand. Verify compatibility with your engine and state emissions rules before buying.
New, used, or rebuilt
New OEM or aftermarket parts come with warranties, but price and availability vary. Used parts are the cheapest option but carry higher uncertainty about remaining life and compatibility. Remanufactured or rebuilt units aim to balance cost and reliability, but be sure to check warranty terms and whether the unit is CARB-compliant if you’re in a state with strict emissions rules.
Where to shop and what to ask
Shop at local auto parts stores, independent shops, and reputable online retailers. When requesting quotes, ask:
- Whether the price includes labor and any shop fees
- If the part is CARB-compliant (for California or other CARB states)
- The warranty length and what it covers
- Whether any additional exhaust work is needed beyond the converter replacement
Engine variants and their impact on pricing
The 2009 Honda Accord offered multiple engines and configurations. Some trims route exhaust through more than one catalytic converter, while others use a single unit. The exact engine and exhaust layout for your car determine how many converters you’ll replace and thus influence the overall price and labor hours.
Summary
Replacing a catalytic converter on a 2009 Honda Accord can cost roughly $330–$850 for the part and installation if you choose an aftermarket, with OEM replacements typically $650–$1,250 installed. Used parts can lower the price further, often to $220–$650 installed, but come with greater risk regarding life expectancy and warranty. Prices vary by engine type, number of converters, regional labor rates, and your state’s emissions requirements. Shop around, confirm fit for your VIN, and consider warranties when making a decision.
