Keep the check engine light off with MagnaFlow Direct-Fit Catalytic Converter 16399. 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. This direct-fit catalytic converter is designed specifically for the 2011-2014 Ford Mustang. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

MagnaFlow now offers a wide variety of universal accessories to help you piece together that one-off system. Whether your looking for band clamps and hangers; X and Y pipe transitions; or just some cut-outs or flanges we have what you are looking for.
