MagnaFlow Conv DF 01-02 Infiniti QX4 3.5L / 01/02/04 Nissan Pathfinder 3.5L (California)

If your 2001-2004 Nissan Pathfinder or 2001-2002 Infiniti QX4 is showing a check engine light related to emissions, it's likely time to replace the catalytic converter. This MagnaFlow California Grade Direct-Fit Catalytic Converter is built to meet strict CARB requirements, ensuring your vehicle stays compliant and the light stays off. It's designed to be a direct replacement, meaning no cutting or welding is needed for installation, making it a job you can often tackle yourself with the right tools.

MagnaFlow puts a lot of effort into making sure these converters fit right and perform well. They use advanced 3D scanning during development to replicate the original equipment's design and fitment. The tubing is mandrel-bent to keep exhaust flowing smoothly, which helps with fuel economy and overall performance. The converter itself is constructed from corrosion-resistant stainless steel, and the single laser fusion weld is designed to prevent leaks. This compact design also helps with thermal efficiency. You'll also find essential gaskets included in the box to help ensure a proper seal during installation.

This converter is specifically tested and certified to meet California Air Resource Board (CARB) guidelines, making it legal for use in California and other states with similar emissions regulations. It interchanges with several original equipment part numbers, giving you confidence that it's designed to function just like the factory unit.
