Eastern Convertors 40268 Catalytic Converter - Front Right

Direct-Fit Catalytic Converter for Pathfinder and QX4

Eastern Convertors 40268 is a direct-fit federal/EPA pre-catalytic converter built for the front right position. It is engineered for 1996-2000 Nissan Pathfinder and 1997-2000 INFINITI QX4 applications, with OE-style dimensions for a precise exhaust replacement.

The DIRECT FIT product line focuses on exact fitment and consistent installation geometry. This converter uses advanced manufacturing methods and a proprietary NANO substrate chemistry to support efficient catalyst loading while helping keep production costs controlled.

What This Part Helps Address

• Failed or restricted front right pre-catalytic converter
• Exhaust flow loss caused by a damaged catalyst substrate
• Check engine light concerns related to converter efficiency
• Exhaust leaks at the inlet or outlet flange connection
• Fitment issues from a converter that does not match OE dimensions

Installation Notes

Confirm the vehicle is a federal/EPA emissions application before ordering. This converter is not for sale or use in California, Colorado, Maine, or New York for vehicles with CA emissions. Verify front right position, flange style, and overall length before installation. The unit uses welded 6-bolt inlet and 3-bolt outlet connections and does not include O2 sensor ports.

Quality Assurance

Eastern Convertors uses automated workstations, spinner welding equipment, and high-speed production lines to build converters to OE dimensions and fitment standards. The NANO substrate chemistry is used to support efficient catalyst loading and consistent converter performance.
