Mercedes-Benz E500 Catalytic Converter - Magnaflow - Direct-Fit - `03-`06. This OEM-grade MagnaFlow direct-fit catalytic converter (part 51706) is designed to replace the factory unit on 2003–2006 E500 models, restoring emissions control and helping prevent OBDII check-engine faults.
Built with mandrel-bent tubing and a spun-body design, this MagnaFlow converter replicates OE flow dynamics to maintain factory performance and fuel economy. The compact, low-mass construction and single laser fusion weld reduce leak points, while high-strength 16-gauge 409 stainless steel offers enhanced corrosion resistance. Hardware and gaskets are included to simplify installation without cutting or welding; Torca AccuSeal® clamps provide even clamp force for a reliable seal and continued serviceability. This unit is designed to meet or exceed Federal emissions requirements set by the EPA for OBDII federally registered vehicles. Not legal for sale or installation in California, Colorado, or New York.
