The typical cost range is about $700 to $2,500 for a full catalytic converter replacement, depending on the part choice (aftermarket vs. OEM) and the labor rate in your area.
Prices vary by engine variant, state regulations (such as CARB requirements in California), and the shop you choose. The article below breaks down the main price drivers, what you can expect to pay for different parts, and strategies to save money.
What you’ll pay: a quick price range
Prices can vary widely by part type and regional labor rates. The following ranges reflect common installed costs in the United States for a 2013 Honda Accord with a typical 4-cylinder engine.
- Parts: Aftermarket catalytic converters (direct-fit or universal) generally cost about $150 to $600 for the part itself, with some higher-end aftermarket options reaching $700. OEM/direct-fit catalytic converters typically run from roughly $600 to $1,800, and in some cases more, depending on the exact engine variant and market.
- Labor: Expect about 1.5 to 3 hours of labor. At typical shop rates of $75 to $150 per hour, labor can range from roughly $112 to $450.
- Additional costs: Disposal fees, gaskets, oxygen sensor replacement if damaged, and possible exhaust-pipe work can add $20 to $200 or more. In California and other CARB-restricted states, a CARB-compliant part may cost more.
Overall, a straightforward replacement using aftermarket parts may land around $400 to $1,000, while an OEM part installed in a higher-cost market or with CARB compliance can push the total toward $1,200 to $2,500 or more.
Parts options: OEM vs. aftermarket
Choosing between OEM and aftermarket catalytic converters has a big impact on total cost and fitment. Here are the common options you’ll encounter.
- OEM direct-fit catalytic converters: Designed to match the factory exhaust layout exactly, typically more expensive but often preferred for fit and emissions compliance. Parts commonly range from about $600 to $1,800, with total installed cost higher in expensive markets or in CARB-regulated areas.
- Aftermarket direct-fit catalytic converters: Built to fit the car’s exhaust system but not produced by the original manufacturer. Parts usually run around $150 to $600, with labor bringing total closer to $300 to $1,000 depending on complexity and local rates.
- Aftermarket universal or mid-range options: May require fabrication or additional piping. Parts can be as low as $100 to $350, but installation complexities often increase labor time and cost.
California and other CARB states often require CARB-approved aftermarket converters to pass emissions standards, which can limit choices and raise costs. Always confirm compliance with your local regulations before purchasing.
Labor and regional considerations
Labor costs are influenced by location, shop rates, and the vehicle’s condition. Rusted or seized fasteners, corroded exhaust components, or sensor issues can extend the job and push labor higher.
- Typical labor window: 1.5–3 hours, subject to access, bolts, and sensor work.
- Regional rate effects: Urban and coastal areas tend to have higher hourly rates than rural regions.
- Regulatory impact: In CARB states, the need for CARB-certified parts can limit options and raise both parts and labor prices.
In practice, a simple replacement in a well-maintained exhaust system is often toward the lower end of the range, while cars with heavy corrosion or sensor-related complications trend toward the upper end.
What to do to save money
Shop smart and plan ahead to minimize costs without compromising safety or emissions compliance. Consider these approaches before committing to a replacement.
- Get multiple quotes from independent shops and dealerships to compare parts and labor.
- Ask for CARB-compliant aftermarket options if you’re in a CARB state; verify certification before purchase.
- Discuss replacing only the failing catalytic converter versus replacing the entire exhaust section if advised by a mechanic.
- Ask about refurbished or remanufactured units where appropriate and ensure they come with a warranty.
- Address warning lights or error codes promptly; addressing related sensors or O2 sensor issues can prevent repeat visits.
Tip: A properly installed converter with the correct part and warranty reduces the likelihood of future failures and additional costs.
Summary
Replacing a catalytic converter on a 2013 Honda Accord typically costs between $700 and $2,500, depending on whether you choose aftermarket or OEM parts, the engine variant, local regulations, and labor rates. In CARB states, compliance requirements can raise both parts and labor costs. To save money, compare quotes, confirm emissions compliance, and consider warranties or remanufactured options where appropriate. Planning ahead and getting multiple estimates helps ensure you get a fair price without compromising safety or emissions performance.
