The cost typically ranges from about $150 to $1,500 before labor, depending on part type, engine configuration, and emissions requirements.
For context, the 2001 Honda Accord offered a 2.3-liter four-cylinder engine in most models and, in some configurations, a 3.0-liter V6. Catalytic converter prices vary by whether you choose an original equipment manufacturer (OEM) part, an aftermarket direct-fit part, or a universal converter, and by whether California or other CARB-regulated markets require CARB-compliant parts. Labor costs vary by shop and region, and the total project price often includes additional emissions-related work.
What affects the price
Prices are driven by several factors that affect both the part itself and the installation. The following factors commonly influence what you’ll pay:
- Engine configuration and the number of catalytic converters in the exhaust system (2.3L four-cylinder vs. 3.0L V6 configurations)
- Part type: OEM direct-fit versus aftermarket direct-fit versus universal/carb-compliant options
- Emission requirements and CARB compliance (California and some other states often demand CARB-approved parts)
- Condition and source: new OEM, new aftermarket, or used/remanufactured parts
- Location and labor rates at the shop
In practice, the price you pay hinges on the engine option, the specific part you choose, and local regulations. Always verify compatibility with your VIN and the emissions rules in your state.
Typical price ranges for a 2001 Honda Accord catalytic converter (parts only)
Prices shown are ballpark ranges for parts in the United States as of 2024–2025. Real-world prices vary by retailer, model, and region. Always confirm the exact part number and fitment for your vehicle.
- OEM direct-fit catalytic converter (2.3L four-cylinder): $600–$1,100
- OEM direct-fit catalytic converter (3.0L V6, if applicable): $900–$1,500
- Aftermarket direct-fit catalytic converter (2.3L four-cylinder): $250–$700
- Aftermarket direct-fit catalytic converter (3.0L V6): $350–$900
- Universal catalytic converter (requires fabrication and welding): $120–$350
Note: Universal converters can require professional installation and may not pass emissions tests in some jurisdictions without additional customization or testing.
Labor costs and total project price
Labor costs depend on the shop, your location, and the complexity of the installation. The typical range is:
- Labor time: approximately 1–3 hours, depending on accessibility and any related work (sensors, flanges, or rusted exhaust components)
- Labor cost: roughly $100–$350, with higher rates in urban or high-cost areas
- Total project price (parts plus labor): commonly $250–$1,800, influenced by part choice and regional labor rates
When budgeting, consider potential extras such as replacing oxygen sensors or exhaust clamps/flanges, which can add to the overall cost.
Where to buy and how to shop
Shop smart by comparing quotes from multiple sources. Common options include:
- Authorized Honda dealers for OEM parts
- Auto parts chains (AutoZone, O'Reilly, Advance Auto) for aftermarket options
- Online retailers (RockAuto, PartsGeek, CarParts.com) for a wide range of brands
- Local exhaust or repair shops that can source parts and perform installation
Pro tip: bring your vehicle identification number (VIN) and check for CARB-compliant parts if you’re in a state with strict emissions rules. Compare warranties and return policies as part of your decision.
Summary
For a 2001 Honda Accord, catalytic converter costs cover a broad range. Parts-only prices typically span from about $120 to $1,500 depending on engine configuration (2.3L four-cylinder vs. 3.0L V6), part type (OEM, aftermarket, or universal), and CARB compliance. Labor generally adds $100 to $350, with total job costs commonly between $250 and $1,800. Always verify compatibility, emissions requirements, and current regional pricing, and obtain multiple quotes to secure the best combination of price and reliability.
