MagnaFlow Conv DF BMW 3 01-06 Front

When you're tackling a catalytic converter replacement on your BMW 3 Series, like the 2001-2005 325i or 2001-2006 325Ci, MagnaFlow's Direct-Fit Catalytic Converter 50287 is a well-built option that aims to make the job straightforward. This unit is designed to meet Federal emissions requirements, helping you keep your vehicle compliant and the check engine light off. It's a solid choice for many BMW models from the early 2000s, including the 325xi, 330Ci, 330i, Z3, and Z4.

What you get in the box are the essential components to get the job done right. This includes the converter itself, along with nuts, bolts, flange gaskets, and flat washers. Using new hardware and gaskets is key to preventing exhaust leaks and ensuring a solid seal, avoiding the need to reuse potentially corroded factory parts. The converter is constructed with high-strength 16-gauge 409 stainless steel tubing for excellent corrosion resistance, and the body features a compact, low-mass design for improved thermal efficiency. MagnaFlow uses 3D scanning during their research and development to ensure the part fits and functions like the original equipment, and the single laser fusion weld is designed to greatly reduce the possibility of leaks.

Installation is intended to be a direct bolt-on process, meaning no cutting or welding is required, which simplifies the job considerably if you have the proper tools. This converter is designed to replicate the OE flow dynamics, aiming to maintain factory performance and fuel efficiency. It's important to note that this converter is EPA-compliant but not CARB approved, so it cannot be shipped to California.
