Two catalytic converters.
In the 1998 Pathfinder, which rides on the R50 platform and commonly uses the VG33E 3.3-liter V6, the exhaust system typically employs a dual catalytic converter setup. That means there are two catalysts in the system, usually one on each bank of the V6. This arrangement helps meet emissions standards by treating exhaust from both banks before it exits the vehicle.
Dual-catalyst setup in the 1998 Pathfinder
The standard configuration for a 1998 Pathfinder with the VG33E engine uses two catalytic converters—one on each bank of the V6. Each converter handles exhaust from its respective bank, with sensors monitoring performance to ensure proper operation.
Where the converters sit on the vehicle
The two catalytic converters are typically located along the exhaust path near the engine, one on the driver’s side bank and one on the passenger’s side bank. They feed into the rest of the exhaust system, including any resonator and the final tailpipe.

- Passenger-side (right) bank catalytic converter, positioned close to the exhaust manifold on that side.
Concluding note: For most US-market Pathfinder models of this era, expect two catalytic converters in the exhaust system—one per bank. If you’re unsure about your specific vehicle, check the VIN or consult the service manual, as regional emissions configurations can vary slightly.
Maintenance considerations
When inspecting or replacing components, verify both converters are functioning and accessible. Issues such as rust, physical damage, or degraded catalysts can affect emissions performance and may trigger diagnostic trouble codes. If in doubt, a professional inspection can confirm whether you have the standard two-cat configuration or a region-specific variation.
Summary
The 1998 Nissan Pathfinder generally features two catalytic converters—one on each bank of the VG33E V6—forming a dual-catalyst exhaust setup. This design is common for emissions compliance and is a standard part of the vehicle’s exhaust system. Always verify with your VIN if you need to confirm the exact configuration for a specific market or trim level.

Can you unclog a catalytic converter instead of replacing it?
Unfortunately, cleaning your catalytic converter does not guarantee it will work effectively afterward. If your converter is defective, cleaning it will not make an impact, and any symptoms present before the cleaning process will return. In the end, if nothing works, a replacement is the way to go.
How many catalytic converters does a Nissan Pathfinder have?
three catalytic converters
The 3.5L V6 engine in the 2016-2020 Pathfinder typically has three catalytic converters. There is one converter for each engine bank (Bank 1 - rear/firewall side, Bank 2 - front/radiator side) integrated with the exhaust manifold, and a third converter located further down the exhaust system.
