BMW 535i Catalytic Converter - Magnaflow - California Direct-Fit - `08-`10 is a direct-fit, CARB-compliant replacement designed for 2008–2010 BMW 535i applications. It provides a factory-style fit and function to help maintain emissions compliance and keep the check engine light off when properly installed.
This MagnaFlow California Grade converter (part 5421013) reproduces OE spun-body geometry to match original flow dynamics. The unit features mandrel-bent tubing and corrosion-resistant stainless steel construction for long service life, and the single laser fusion weld reduces potential leak points compared with multi-piece assemblies. MagnaFlow’s R&D uses 3D scanning during development to help ensure accurate fitment; this converter installs without cutting or welding using the supplied gaskets and hardware. It is designed to fit 2008–2010 BMW 535i models (including 2008 535xi) and interchanges with OE numbers 18 30 7 565 684 and 18 30 7 565 688.
