Typically, a Honda Accord catalytic converter costs about $200 to $2,500 for the part, with installed prices usually $1,000 to $3,000 depending on model year, engine type, and local labor rates.
What affects the price
Prices vary widely depending on the part type, emissions requirements, and labor. The following factors most commonly affect the total cost:
- Part type: OEM Honda catalysts from a dealer are generally more expensive than aftermarket options.
- Emissions compliance: California CARB-compliant parts often cost more and are required for vehicles in CA and sometimes nearby states.
- Engine and model year: The Accord’s engine (e.g., 1.5L vs 2.0L) and generation determine the exact part number and price.
- Installation complexity: Accessibility of the exhaust system, rust, and mounting hardware can affect labor time.
- Fitment: Direct-fit replacements install with minimal modification; universal or welded solutions require additional work and risk fit issues.
Conclusion: The price range reflects both the part selection and the labor environment, so shopping around and confirming emissions compliance is important.
Cost options and typical ranges
Prices shown are general ranges as of 2026 and can vary by year, engine, and location. The ranges cover common sourcing options.
- OEM Honda catalytic converter (new, direct from dealer): Part price typically $600–$1,800; installation labor generally $100–$300; total installed price around $700–$2,100 (California variants and dealership services can push higher).
- OEM replacement from a dealer or authorized distributor (brand-new OEM): Similar to the above, sometimes slightly less depending on promotions and availability.
- Aftermarket direct-fit catalytic converter (CARB-compliant for Honda Accord): Part price typically $300–$900; labor $100–$250; total installed price often $400–$1,400.
- Aftermarket universal catalytic converter (requires cutting/welding): Part price often $50–$250; installation labor $200–$600; total installed price can be $350–$1,000, with potential fit and emissions considerations.
- Used or salvaged catalytic converter: Part price typically $100–$400; labor similar to new parts; total often $300–$900.
Conclusion: Your best value depends on whether you prioritize guaranteed fit, warranty, and emissions compliance versus upfront dollars.
OEM vs aftermarket: which to choose?
OEM parts offer guaranteed fit and typically come with a stronger warranty, but at higher prices. Aftermarket options can save money and, if CARB-compliant, meet emissions requirements while offering similar performance. California residents should verify CARB approval for aftermarket replacements.
Tips to save money
Before shopping, consider these strategies to reduce the total cost without sacrificing reliability or compliance:
- Compare multiple quotes from independent shops, not just the dealership.
- Ask about warranty terms on the catalytic converter and labor.
- Check for CARB-compliant aftermarket options if you’re in California or a CARB-heavy state.
- Consider reputable used or salvaged parts if you’re on a tight budget, understanding the risk of wear.
- Plan timing to avoid peak labor periods; some shops offer promotions or discounts on replacement services.
Conclusion: thoughtful shopping and clear emissions requirements can dramatically affect total cost and long-term satisfaction.
Summary
The cost to replace a Honda Accord catalytic converter varies widely—from a few hundred dollars for a basic used part to several thousand when opting for OEM units and professional installation in higher-cost regions. Key drivers include OEM vs aftermarket choice, CARB compliance, engine and year, and labor rates. Prospective buyers should compare several quotes, confirm emissions compliance, and weigh the value of warranty and fit when deciding where to purchase and have the part installed.
