Keep the check engine light off with MagnaFlow HM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 50805. 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 2002-2006 Nissan Altima and 2002-2006 Nissan Sentra, this direct-fit catalytic converter also interchanges with OE parts 14002-8J008 and 14002-9J305, among others. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation. 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 Federal/EPA Emission systems.

Product Features:

• Expertly crafted to replicate OEM-like flow dynamics, maintaining factory performance and fuel efficiency.
• Simplifies installation with essential gaskets and hardware being included in the box.
• Your trusted source for EPA-compliant catalytic converters, providing assurance of genuine compliance while delivering quality that will last.
