Prices range from about $150–$600 for aftermarket direct-fit catalytic converters to roughly $800–$1,600 per converter for OEM Honda parts, with installation adding roughly $100–$300 per unit. If your Accord uses two converters, expect the total to be about double. Prices vary by engine variant (1.5L vs 2.0L) and by whether you need a single converter or multiple units.
Price ranges and options
Understanding the main choices helps shoppers compare quotes and stay compliant with emissions rules.
- OEM Honda catalytic converter (direct-fit): typically $800–$1,400 per converter. This is the most expensive option, but it offers exact fit and guaranteed emissions compatibility.
- Aftermarket direct-fit catalytic converter (brand-name like Walker, MagnaFlow, Bosal): roughly $150–$600 per converter, depending on engine type and model year.
- Universal aftermarket catalytic converter (requires fabrication and welding): about $50–$300 for the part, plus higher labor costs for installation and proper sensor placement.
- Remanufactured or rebuilt units: often $100–$400, but reliability and warranty can vary; not always permitted for new-car emissions compliance.
Note: If your 2019 Accord uses more than one catalytic converter, you’ll pay for each converter, so total parts cost and installation will be higher.
Installed cost scenarios
Labor costs add to the price, and installation quality affects both performance and emissions compliance.
- One converter installed (typical for some 2019 Accord configurations):
- Aftermarket direct-fit: roughly $300–$700 installed.
- OEM Honda: roughly $1,000–$1,800 installed.
- Two converters installed (some engines or trims may use two):
- Aftermarket: roughly $600–$1,400 installed.
- OEM Honda: roughly $2,000–$3,000 installed.
Overall installed costs can vary by shop rates and region; always request a written quote that itemizes the converter cost, labor, and any related sensors or gaskets.
Other considerations
Compliance, warranty, and vehicle emissions rules influence choices. In many regions, including California, catalytic converters must be CARB-compliant to be legal for road use. Using universal or non-CARB-approved parts can result in a failed inspection or fines. Verify part numbers with your VIN and engine type before purchase, and ensure the installer is experienced with emissions components.
Where to buy and how to verify
Shop through authorized Honda parts dealers, reputable auto parts retailers, or trusted repair shops. Compare quotes for the exact VIN, engine variant, and emission requirements. Check for a warranty on both parts and labor, and beware of very low prices that may indicate non-compliant components or poor fit.
Summary
For a 2019 Honda Accord, catalytic converter prices typically range from aftermarket direct-fit units around $150–$600 per converter to OEM Honda parts around $800–$1,600 per converter, with installation adding about $100–$300 per unit. If two converters are required, expect roughly double those figures. Always verify CARB compliance where required, confirm part numbers for your VIN, and obtain multiple quotes to ensure you’re getting a fair price.
