Magnaflow 2015 M3 3 Underbody Direct Fit Converter

Magnaflow is well-known for making exhaust components that perform well and last. This direct-fit catalytic converter is built to keep your 2015-2020 BMW M4 running smoothly and legally. It’s designed to replace your original converter, helping to ensure your check engine light stays off and your vehicle meets federal emissions standards.

This converter uses strong 16-gauge 409 stainless steel tubing, which is great for resisting corrosion and giving you a long service life. The tubing is mandrel-bent to match the original equipment's design and geometry, so it maintains factory performance and fuel efficiency. Magnaflow uses advanced 3D scanning during development to make sure this part fits just like the original. The single laser fusion weld is designed to reduce the chance of leaks, and its compact, low-mass build helps with thermal efficiency. You also get the necessary gaskets and hardware, like split lock washers, bolts, flat washers, and nuts, making installation straightforward without needing to cut or weld.

This converter is designed to meet or exceed EPA emissions requirements for OBDII Federally registered vehicles. Please note that this part is not CARB approved and cannot be shipped to California.
