Two catalytic converters.
Most 2007 Honda CR-Vs use a dual-cat exhaust arrangement: a close-coupled catalytic converter near the engine and a second catalytic converter further back in the exhaust system. This layout helps the catalytic converter reach operating temperature quickly and provides efficient emissions reduction during normal driving.
Locations and roles
The common dual-cat setup places one cat close to the engine to heat up quickly (pre-cat) and a second main cat further along the exhaust path. Each converter reduces pollutants before exhaust gases exit the vehicle.
- Close-coupled catalytic converter (pre-cat): located near the exhaust manifold, designed to heat rapidly and begin emissions control as soon as the engine starts.
- Main catalytic converter: located downstream in the exhaust path, typically after the mid-pipe and before the resonator (where it handles the majority of emissions reduction during steady operation).
In some markets or trims, the exact routing can vary slightly, but the dual-cat arrangement remains the common baseline for 2007 CR-V models.
Verifying the converter count on your vehicle
To confirm your specific vehicle’s setup, use these verification steps or sources.
- Visual inspection: safely lift the vehicle and count the catalytic converters along the exhaust path; you should see two distinct catalytic units.
- Consult service documentation: your owner’s manual or Honda service manual for your VIN may specify a dual-cat layout.
- VIN and dealer support: provide your VIN to a Honda dealer or service portal to obtain precise emissions equipment details.
- Sensor configuration: two upstream O2 sensors can indicate two cats, but sensor layouts vary by market and engine code.
If you’re unsure, consult a qualified mechanic who can verify the exact configuration for your vehicle’s engine and market.
Summary
The 2007 Honda CR-V typically features two catalytic converters—one near the engine and one further back in the exhaust—designed to meet emissions standards in the US and other markets. Always verify the exact arrangement for your specific vehicle using manuals or dealer support.
