Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51991 for your 2001-2004 Nissan Frontier or 2001-2004 Nissan Xterra. With features including free-flowing mandrel-bent tubing and highly corrosion resistant stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment.

By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. Designed to fit the 2001-2004 Nissan Frontier and 2001-2004 Nissan Xterra, this direct-fit catalytic converter also interchanges with OE parts 14002-3S600 and 14002-3S610, among others. Avoid potential exhaust leaks by using the included gaskets to get a proper seal.

This replacement part is designed to meet or exceed Federal emissions requirements set forth by the EPA, complying with legal standards for OBDII Federally registered vehicles with California or Federal/EPA Emission systems. MagnaFlow Limited 5 Year / 50K Mile Warranty (Details HERE).
