- Two catalytic converters (dual system). Parts costs: aftermarket for both around $300–$700; OEM Honda for both around $800–$1,600.
Conclusion: The number of converters and the choice of parts are the main price drivers for a 2018 Civic.
Getting precise quotes for your car
To obtain accurate numbers, gather your vehicle information and request quotes that break out parts vs labor and include any required related items.
- Have your VIN ready and confirm whether your model uses one or two catalytic converters.
- Ask for both OEM and aftermarket options with price and warranty details.
- Check whether the quote includes sensors, gaskets, clamps, and labor, and whether any emissions test requirements apply.
Conclusion: Collect multiple quotes to compare total installed costs and warranty terms.
Labor, installation time, and warranties
Labor for replacing catalytic converter(s) on a 2018 Civic typically runs about 1–2 hours per converter, depending on access and sensor work. OEM parts often come with longer warranties (often 5–8 years or limited mileage), while aftermarket parts vary by manufacturer (commonly 1–3 years). Verify coverage details with the shop.
Tips to avoid surprises
Ensure the quote includes all necessary items (e.g., sensors, gaskets) and that the part matches your VIN. Ask about recycled or remanufactured options only if you trust the supplier and the warranty is explicit.
