Typically, a replacement costs about $1,000 to $1,800 total when using a new OEM catalytic converter, including labor. Costs vary by engine type, parts quality, and local shop rates.
The 2008 Honda Accord offers a few different engine configurations. The common 2.4-liter four-cylinder model usually uses a single catalytic converter, while some V6 setups may involve more than one. Your exact price depends on whether you choose an OEM part or an aftermarket equivalent, and on your shop’s labor rate. The following guidance outlines typical costs, what drives them, and how to get an accurate quote for your specific car.
Cost ranges by configuration
Single catalytic converter (most 4-cylinder Accords)
Estimates reflect a single catalytic converter replacement with an OEM part, including labor.
- Parts (OEM cat): typically about $600–$1,200
- Labor: about $150–$300
- Typical total: roughly $750–$1,500
Note: Prices vary by region and shop; some OEM replacements may run higher especially if the exhaust system or sensors require additional work.
Two catalytic converters (V6 or dual-cat setups)
Some 2008 Accords with the V6 engine can have two catalytic converters or a more complex exhaust path requiring two units.
- Parts: $1,000–$2,000 per cat (range varies by OEM vs aftermarket)
- Labor: $200–$500 (for both cats combined, depending on access and welding)
- Typical total: approximately $1,800–$4,500+
For many owners, this is the upper end of the replacement cost spectrum.
Aftermarket or universal catalytic converters
Aftermarket or universal catalytic converters can be cheaper, but may require fabrication and may not pass certain emissions inspections depending on the state.
- Parts: about $150–$600
- Labor: about $100–$400
- Typical total: roughly $250–$1,000
Always confirm CARB-compliance (or equivalent in your state) before opting for an aftermarket or universal cat.
What affects the price
Multiple factors influence the final bill, from the car’s engine setup to your local labor rates and emissions requirements.
- Engine type and number of catalytic converters
- OEM vs aftermarket parts; CARB-compliant or region-specific requirements
- Labor rates and shop location
- Additional work required (oxygen sensors, clamps, hangers, wiring, or exhaust manifold damage)
- Emissions testing or state inspection requirements
- Warranty coverage on parts and labor
- Theft-related damage and associated anti-tamper modifications
Understanding these factors helps you compare quotes and avoid surprises at the counter.
Getting an accurate quote
To obtain a precise estimate for your specific Accord, follow these steps:
- Call or visit multiple local shops and ask for a written quote with a breakdown (parts, labor, tax, any shop fees).
- Have your VIN and engine type handy to ensure the correct catalytic converter is identified.
- Ask for OEM part numbers and confirm CARB compliance if you’re in a state with strict emissions rules.
- Inquire about any additional work that might be needed (sensors, oxygen sensors, or gasket replacements).
Getting several quotes and asking for a full breakdown helps you avoid surprises and choose the best value.
Summary
Replacing a catalytic converter in a 2008 Honda Accord typically falls in the $750–$1,500 range for a single OEM cat, with higher costs if a second cat is involved or if OEM parts are chosen for a dual-cat setup. Aftermarket or universal cats reduce part costs but may carry compliance risks. The exact price depends on engine configuration, parts choice, local labor rates, and emissions requirements. Shop around, compare written quotes, and ensure the chosen solution meets your local regulations—then budget for possible ancillary work like sensors or exhaust fittings.
