BMW 535i Performance Exhaust - MagnaFlow - Direct Fit Catalytic Converter - `08-`10. This MagnaFlow California-grade direct-fit catalytic converter (part 5421014) replaces the factory unit to maintain emissions compliance and proper engine operation.
Designed for 2008–2010 BMW 535i (and 2008 535xi), this direct-fit converter replicates OE spun-body design and installs without cutting or welding using the included gaskets and hardware. MagnaFlow’s R&D uses 3D scanning to match OE geometry, and the compact, low-mass design helps preserve thermal efficiency and factory flow characteristics. It is CARB-compliant for legal sale in California and other CARB states when the EO and Engine Family Number match the vehicle’s requirements.
Features
- Direct-fit replacement for 2008–2010 BMW 535i (interchanges with OE 18 30 7 565 685 / 18 30 7 565 689)
- California CARB-compliant (meets requirements when EO/EFN apply)
- Mandrel-bent tubing and OE-like flow dynamics for consistent engine performance
- High-strength 16 gauge 409 stainless steel construction and spun-body design
- Single laser fusion weld to reduce potential leak points; includes necessary gaskets and hardware
