MagnaFlow is well-known for making exhaust components that flow well and last a long time. This direct-fit catalytic converter is built to keep your check engine light off and meet Federal emissions standards for OBDII vehicles. It’s designed to replace the original converter on a range of BMW models, including the 128i, 328i, and 330i, ensuring your vehicle runs cleanly and legally.

This converter uses free-flowing, mandrel-bent tubing made from highly corrosion-resistant stainless steel, so it’s built to handle the elements and last. MagnaFlow uses advanced 3D scanning during development to make sure this part fits just like the original equipment. The body design replicates the OE spun body, and a single laser fusion weld is used to greatly reduce the chance of leaks. Its compact, low-mass design also helps with thermal efficiency. You won't need to cut or weld anything to install this; it’s designed as a direct bolt-on replacement. MagnaFlow includes the necessary gaskets and hardware, so you don't have to worry about reusing old, corroded parts for a solid seal.

This converter is designed to meet or exceed Federal emissions requirements set forth by the EPA. Please note that this converter is not CARB approved and cannot be shipped to California. It interchanges with several OE part numbers, including 18 30 7 547 840 and 18 40 7 545 309.
