BMW M3 Catalytic Converter - MagnaFlow - Direct Fit - `15-`18. This OEM-grade, direct-fit catalytic converter is built to replace the factory underbody unit on 2015–2018 BMW M3 applications while preserving factory fit and operation.
MagnaFlow designs this converter using precision 3D metrology to replicate OE spun-body geometry and flow dynamics. The unit is Federal/EPA compliant and engineered for a direct-fit installation with mandrel-bent tubing and high-strength stainless construction, reducing the need for cutting or welding. A single laser fusion weld mirrors the OE approach to minimize leak potential and the compact, low-mass design improves thermal efficiency and retains factory fuel economy and engine performance. Hardware and gaskets are included to simplify installation, and the part interchanges with OE part 18 32 7 848 044. Designed to fit 2015–2020 M4 and 2015–2018 M3 vehicles.
