Magnaflow 49783 Features:
Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 49783. 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 1999-2003 BMW 540i, 1999-2001 BMW 740iL, and more, this direct-fit catalytic converter also interchanges with OE part 11 62 1 437 496. 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 California or Federal/EPA Emission systems.
