Product Details

Starting with its highly corrosion-resistant stainless steel construction, this MagnaFlow direct-fit catalytic converter is built to last. It’s designed to keep your check engine light off by meeting Federal emissions requirements for OBDII Federally registered vehicles with Federal/EPA Emission systems. This converter is a solid option for a range of BMW models, including the 325i, 330xi, and X3, ensuring your vehicle complies with emissions standards without needing to reuse old, corroded factory parts.

MagnaFlow uses advanced 3D scanning during their research and development to ensure this converter fits and functions just like the original equipment. The spun body design replicates the OE look and feel, and a single laser fusion weld greatly reduces the chance of leaks. Its compact, low-mass design also contributes to better thermal efficiency. The free-flowing, mandrel-bent tubing helps maintain factory performance and fuel efficiency, so you won't sacrifice driveability for compliance. Installation is made simpler because essential gaskets and hardware are included in the box, meaning no cutting or welding is required if you have the proper tools.

This converter interchanges with several OE part numbers, including 18 40 7 514 503 and 18 40 7 514 505. Please note that this converter is not CARB approved and cannot be shipped to California.
