MagnaFlow Conv DF 09-10 528i 3.0L Rear

When it's time to replace the catalytic converter on your 2008-2011 BMW 528i, this direct-fit unit from Magnaflow is built to keep your check engine light off and your vehicle running cleanly. It's designed to meet or exceed Federal emissions requirements set forth by the EPA, making it a legal replacement for OBDII Federally registered vehicles, including those with California or Federal/EPA Emission systems. This converter is specifically engineered to function like the original equipment, ensuring your car maintains its factory performance and fuel efficiency.

You'll get everything you need for a straightforward installation, as Magnaflow includes essential gaskets and hardware in the box. This means you won't have to reuse corroded factory parts or worry about a leaking seal. The converter itself is constructed with high-strength 16-gauge 409 stainless steel tubing for excellent corrosion resistance and a long service life. Magnaflow uses a compact, low-mass design with a single laser fusion weld, which helps with thermal efficiency and greatly reduces the chance of leaks. The free-flowing, mandrel-bent tubing is also key to maintaining factory performance dynamics.

This part is designed for a direct fit, meaning no cutting or welding is required for installation, just use the proper tools. It interchanges with OE parts 18 40 7 563 732 and 18 40 7 596 876. Please note that this converter is not CARB approved and cannot be shipped to California.
