BMW M4 Catalytic Converter - Magnaflow - Direct Fit - `15-`20. This OEM-grade, federal/EPA-compliant direct-fit converter is designed as a replacement for the factory unit on 2015–2020 BMW M4 (and compatible with 2015–2018 M3 applications).
Built to replicate OE form and function, this MagnaFlow converter uses a spun-body design with a single laser fusion weld to reduce leak points and a compact, low-mass profile for thermal efficiency. Mandrel-bent tubing preserves factory-like flow geometry to support engine operation and fuel economy. Constructed from corrosion-resistant 16 gauge 409 stainless steel, it includes the necessary gaskets and hardware for a straightforward installation without cutting or welding. This part interchanges with OE number 18 32 7 848 044 and is intended to meet Federal emissions requirements for EPA-registered vehicles. Note: this federal converter is not legal for sale or installation in California, Colorado, or New York.
