Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 52925. 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 2015 BMW M4 and 2015 BMW M3, this direct-fit catalytic converter also interchanges with OE part 18 30 7 851 178. Hardware is included to eliminate the hassle of working with corroded factory parts.

Does the job. Made a set of battery cables that look professionally manufactured using a hydraulic crimper. The heat shrink adds a nice touch.
