Product Details

MagnaFlow is known for making exhaust components that flow well and last a long time. This direct-fit catalytic converter, part number 24512, is designed to keep your BMW 3 Series running cleanly and the check engine light off. It's built to meet Federal emissions requirements for OBDII vehicles registered in states with Federal/EPA emission systems.

This converter is constructed from corrosion-resistant stainless steel, with free-flowing mandrel-bent tubing that maintains factory performance and fuel efficiency. MagnaFlow uses 3D scanning during development to ensure a precise fit, just like the original equipment. The spun body design replicates the OE style, and a single laser fusion weld helps prevent leaks. Its compact, low-mass design also contributes to better thermal efficiency. Installation is straightforward, as it's designed to bolt directly in place of your original converter, meaning no cutting or welding is needed. Essential gaskets and hardware are included to simplify the process.

This part fits a range of BMW 3 Series models, including the 2006 BMW 325i, 2007-2013 BMW 328i, and 2009-2013 BMW 328i xDrive, among others. It's a direct replacement for OE parts 18 30 7 547 840 and 18 30 7 566 937. Please note that this converter is not CARB approved and cannot be shipped to California.
