Features & Benefits

Warranty

MagnaFlow and NAPA Auto Parts have teamed up to bring industry-leading exhaust solutions to more drivers, combining superior engineering and long-lasting reliability to keep vehicles performing at their best. This partnership delivers innovation, quality, and durability—backed by a trusted brand and powered by "NAPA KNOW HOW". Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-457. 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 2012 Ram 1500, 2012-2018 Ram 2500, and more, this direct-fit catalytic converter also interchanges with OE parts 6814 9940AC and 6814 9940AB. 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.
