BMW M4 Catalytic Converter - Underbody - Magnaflow - Direct Fit Converter - `15-`20 free shipping

BMW M4 Catalytic Converter - Underbody - Magnaflow - Direct Fit Converter - `15-`20. This OEM-grade, direct-fit underbody catalytic converter is designed for fit and function on 2015–2020 BMW M4 (and compatible with 2015–2018 M3 applications), offering a reliable replacement that retains factory flow characteristics.

Built by MagnaFlow using precise 3D-scanned dimensions, this converter replicates OE spun-body design and uses high-corrosion-resistant stainless steel tubing and a single laser fusion weld to reduce leak points. The compact, low-mass construction helps thermal efficiency while mandrel-bent tubing preserves exhaust geometry for consistent engine performance and fuel economy. Hardware is included to simplify installation without cutting or welding when using proper tools. This part interchanges with OE numbers 18 30 8 094 373 and 18 30 7 851 178 and is manufactured to meet Federal/EPA emissions requirements for applicable vehicles.

Features

Direct-fit OEM-style spun body design for precise fit
High-corrosion 409 stainless steel tubing and 410 stainless hangers
Mandrel-bent tubing for maintained exhaust flow and efficiency
Single laser fusion weld to minimize potential leak points
Includes necessary hardware and Torca AccuSeal® style clamps for reliable sealing
