MagnaFlow Conv DF 01-03 Infiniti QX4 3.5L P/S Rear / 01-04 Nissan Pathfinder 3.5L P/S Rear

If your check engine light is on and you suspect a catalytic converter issue on your 1998-2004 Nissan Pathfinder or 1998-2003 Infiniti QX4, this direct-fit converter from Magnaflow is a solid option. It's designed to meet Federal emissions requirements, helping you pass inspections and keep that warning light off.

This converter is built with corrosion-resistant stainless steel tubing, including a high-strength 16-gauge 409 stainless steel construction for the main pipe, and durable 308 stainless steel MIG welds. The tubing is mandrel-bent to ensure smooth exhaust flow, mimicking the original equipment's design to maintain factory performance and fuel efficiency. Magnaflow uses advanced 3D scanning during development to ensure this converter fits and functions just like the part it replaces, and the single laser fusion weld helps prevent exhaust leaks. Installation is straightforward as it's designed to bolt directly in place, with no cutting or welding needed, and it includes the necessary gaskets for a proper seal.

This converter is EPA-compliant for Federal emissions systems. It interchanges with several OE part numbers, including 14004-4W000 and 20010-1W611. Please note that this converter is not CARB approved and cannot be shipped to California.
