The majority of Honda Civic Hybrid models use two catalytic converters in the exhaust system: a close-coupled pre-catalytic converter near the engine and a downstream secondary catalytic converter further back.
There are exceptions: some older or regional variants may use a single catalytic converter. The exact arrangement depends on the model year and market, so check your vehicle’s documentation or VIN-specific service information for precise details.
Here's how the typical configurations break down and what to look for when inspecting or replacing exhaust components.
Before describing specifics, note that the two-catalytic-converter arrangement is common for modern Civics in many regions, but variations do occur based on emissions standards and production year.
- Two-converter setup: a close-coupled pre-cat near the exhaust manifold and a downstream main catalytic converter located further back in the exhaust path.
- Single catalytic converter in some older or market-specific variants: certain early-generation or non-U.S. market Civics may use only one cat.
In practice, most Civic Hybrids you encounter will have two catalytic converters, though you should verify for your specific year and market configuration.
What to check by model year
Recent generations (approximately 2016 onward)
In many recent Civic Hybrid models, expect a two-cat arrangement. The first cat is typically close to the engine, with a second cat positioned downstream in the mid-to-rear exhaust section. This setup supports stricter emissions targets and hybrid-specific fueling strategies.
Earlier generations and non-U.S. markets
Earlier Civics or variants built for certain markets may employ a single catalytic converter. If you’re working on an older Civic Hybrid or a region-specific model, confirm the configuration with the service manual or by inspecting the exhaust layout under the vehicle.
Summary: The Honda Civic Hybrid typically has two catalytic converters, but configurations can vary by year and market. Always verify with model-specific documentation or a qualified technician.
Summary
Most Honda Civic Hybrid models rely on two catalytic converters in the exhaust system—one near the engine and a second downstream. Some older or regional variants may use a single catalytic converter. For precise configuration, consult the vehicle’s manual or VIN-based service information.

Why do hybrids have more expensive catalytic converters?
Catalytic converters in hybrids
This is due to hybrid catalytic converters operating at a lower temperature since the combustion engine does not operate full-time. To mitigate the natural temperature difference, hybrid catalytic converters use precious metals including platinum, palladium, and rhodium.
Does a Honda Civic Hybrid have a catalytic converter?
Unlike some of its rivals that lose pep when emissions hardware gets older, the Civic Hybrid retains crisp acceleration due to the consistency of its Catalytic Converter, which ensures the Honda nameplate's standing as a smart, efficient, trustworthy daily companion.
