Typically, replacing a Honda Accord catalytic converter costs about $1,000 to $2,500, depending on parts, labor, and whether your model uses one or two converters. OEM replacements tend to be pricier than aftermarket parts, and dealership service usually costs more than independent shops.
Cost drivers
Costs vary based on the part you choose, local labor rates, model year, and whether your Accord has one or two catalytic converters. Understanding these factors helps you get a realistic quote.
Parts options
Choosing the right parts option – OEM, direct-fit aftermarket, or a universal converter – has a major impact on price and fit. The number of catalytic converters (one or two) and engine variant also affect the final bill.
- OEM direct-fit catalytic converter: commonly $600–$1,300 for the part; labor typically $150–$350; total often $750–$1,650. Some models with two converters can push higher.
- Aftermarket direct-fit catalytic converter: commonly $350–$900 for the part; labor $150–$350; total $500–$1,250.
- Universal or semi-universal catalytic converters (requires modification for fit): part $150–$450; labor higher due to fabrication; total often $350–$1,000+
In practice, OEM parts are more expensive but provide guaranteed fit, emissions compliance, and warranties, while aftermarket parts can save money but vary by brand and coverage.
Labor costs and regional variation
Labor charges depend on shop type and location. Dealerships typically cost more per hour than independent shops, and urban areas generally have higher rates than rural areas. The time to replace a cat can range from about 1 to 3 hours, depending on accessibility and whether multiple converters are involved.
Typical labor ranges
- Independent shop: roughly $75–$150 per hour; total labor commonly 1–3 hours
- Dealership: roughly $120–$200+ per hour; total labor commonly 1–3 hours
Always request a written estimate that itemizes parts and labor before authorizing work.
Typical total price ranges by scenario
These ranges reflect current market prices across the United States as of 2024–2026. Actual quotes depend on your Accord’s model year, engine, and local labor rates.
- Single catalytic converter, aftermarket parts, independent shop: $450–$1,000
- Single catalytic converter, OEM parts, independent shop: $750–$1,650
- Single catalytic converter, OEM parts, dealership: $1,000–$2,000
- Two catalytic converters (common on some Accord models), aftermarket parts, independent shop: $900–$2,000
- Two catalytic converters (OEM parts or dealership), dealership: $1,800–$3,000
Note: Some Accord variants use two catalytic converters; the total cost can rise accordingly. The most economical route is often an aftermarket direct-fit part installed by a reputable independent shop, while the most expensive option is OEM/Dealership replacement for two cats.
Warranty and safety considerations
Most aftermarket catalytic converters come with a warranty ranging from 1 to 5 years or a mileage limit, while OEM parts typically carry a factory warranty. Check both the part warranty and labor warranty with the shop, and ensure the replacement complies with local emissions requirements and will pass inspections where applicable.
How to save and get a fair price
To reduce cost without compromising safety or emissions compliance, consider the following steps.
- Shop around: obtain multiple estimates from independent shops and dealers.
- Ask about parts options: confirm fit and emissions compliance for your specific model year.
- Check for warranties: ensure the part and labor are covered for a reasonable period.
- Compare total quotes, not just the upfront price: some shops include extra services or hidden fees.
By comparing quotes and understanding the options, you can balance cost with reliability and compliance.
Summary
Replacing a Honda Accord catalytic converter typically costs between about $1,000 and $2,500, with variations driven by the number of converters, part type (OEM vs aftermarket), and local labor rates. Always obtain multiple, written estimates and verify emissions compliance to avoid future issues.
