A 2018 Nissan Rogue with the common 2.5L four-cylinder engine typically has two catalytic converters in its exhaust system. One is located near the engine as a pre-catalytic converter, and a second downstream catalytic converter handles the majority of emissions control.
Standard gasoline Rogue configuration
For the gasoline-powered Rogue models sold in North America, the two-catalyst arrangement is the norm. This setup helps meet emissions requirements across a range of operating conditions.
Two catalytic converters: what they are
- Pre-catalytic converter: Located close to the exhaust manifold; starts reducing pollutants early in the exhaust stream.
- Main catalytic converter: Positioned downstream; completes pollutant reduction before exhaust exits the vehicle.
In combination, these two converters are designed to comply with federal and state emissions standards while preserving engine performance and fuel efficiency.
Variations by market and drivetrain
While two catalytic converters are standard for most gasoline Rogues, variations can occur depending on the market, regulatory requirements, or if the vehicle is a Rogue Hybrid. Always verify the exact configuration for your specific vehicle using official documentation or a Nissan dealer.
Common variations to be aware of
- Rogue Hybrid (if equipped): Hybrid configurations can alter exhaust routing, and some versions may handle emissions with a different layout while still using catalytic converters.
- Regional differences: Emissions standards in different countries or regions can influence the number and placement of catalytic converters.
To be certain, check the vehicle’s VIN, service manuals, or contact a Nissan dealership for the exact configuration of a specific 2018 Rogue.
Summary
Bottom line: the typical 2018 Nissan Rogue gasoline model uses two catalytic converters in series—one near the engine as a pre-catalyst and a downstream main catalyst. Variations can exist for Rogue Hybrids or regional specifications, so when in doubt, refer to official documentation or a dealer for the precise setup.
