The typical installed cost is about $800 to $2,500, depending on model year, engine, whether you use OEM or aftermarket parts, and local labor rates.
What affects the price
Several factors influence the final bill when replacing a catalytic converter on a Civic.
- Part type: OEM Honda catalytic converters tend to be more expensive than aftermarket direct-fit replacements, but they may come with longer warranties and guaranteed fit.
- Vehicle configuration: Some Civics have a single catalytic converter; others have two (pre-cat and main cat). The number of converters affects both parts and labor costs.
- Engine and model year: Different engines and generations use different catalytic converter designs and sensor configurations, which can alter part price and labor time.
- Labor costs and accessibility: Regional labor rates vary; limited access or corrosion can increase shop time and cost.
- Additional parts and services: O2 sensors, gaskets, clamps, and mounting hardware may need replacement, adding to the total.
Conclusion: Prices reflect a blend of parts and labor, plus the vehicle’s exact configuration. The ranges below offer budgeting benchmarks.
Typical cost ranges
To provide a baseline, here are general ranges for common Civic configurations and markets.
- OEM catalytic converter (part): roughly $500 to $1,100
- Aftermarket/direct-fit catalytic converter (part): roughly $150 to $600
- Labor to replace (1.0–4.0 hours, depending on access and shop): roughly $100 to $700
- Taxes and shop fees vary by location
Note: In high-volume markets or for Civics with two converters, total installed costs can be higher, especially if additional components are required or if labor rates are steep.
Cost scenarios by configuration
Single catalytic converter (most Civics)
For a Civic with a single catalytic converter, typical installed costs fall in the following ranges, depending on the part choice and local rates.
- OEM parts scenario: about $800 to $1,800 installed
- Aftermarket parts scenario: about $400 to $1,000 installed
Conclusion: Most owners see a total installed price around the $900–$1,800 band, with regional and shop differences.
Dual catalytic converters or more complex exhaust
On Civic generations that use two catalysts (pre-cat and main cat) or have a more complex exhaust routed to two converters, the installed cost rises accordingly.
- OEM parts scenario: roughly $1,200 to $2,200 per converter, potentially higher for two units
- Aftermarket parts scenario: roughly $300 to $1,200 per converter, depending on design and fitment
Conclusion: Expect higher costs when dealing with two converters and older or high-mileage vehicles, as labor time and parts may increase.
What to do next
To get an accurate quote for your exact Civic, gather quotes from local shops and confirm whether your vehicle has one or two converters, plus whether sensors or gaskets need replacement. Ask shops to itemize parts, labor, and taxes, and verify if there is a warranty on the replaced component.
Summary
The cost to replace a catalytic converter on a Honda Civic varies widely based on part type (OEM vs aftermarket), the number of converters, engine configuration, and local labor rates. Typical installed ranges are roughly $800–$2,500, with higher figures in complex or high-cost markets. Always obtain multiple quotes, confirm exactly which components are being replaced, and check warranties to ensure best value and proper fit.
