MagnaFlow Conv DF BMW 04-05 330XI 3.0L / 04-06 X3 2.5L/3.0L

When your check engine light comes on for emissions issues, this direct-fit catalytic converter from Magnaflow is what you need to get your 2001-2005 BMW 330xi or 2004-2006 BMW X3 back to proper working order. You'll receive the converter itself, along with the necessary gaskets and hardware to ensure a leak-free installation without needing to reuse old, corroded factory parts. This converter is designed to meet Federal emissions requirements set forth by the EPA, so you can be confident it's compliant for OBDII Federally registered vehicles.

Magnaflow builds this converter with free-flowing, mandrel-bent tubing and a spun body design that replicates the original equipment. This not only helps maintain factory performance and fuel efficiency but also allows for greater thermal efficiency due to its compact, low-mass construction. The tubing is made from high-strength 16-gauge 409 stainless steel for excellent corrosion resistance, and the body is constructed from 308 stainless steel with durable MIG welds, ensuring a long service life. Magnaflow uses advanced 3D scanning during their research and development to ensure this part fits and functions just like the original.

Because this is a direct-fit unit, installation is straightforward and doesn't require any cutting or welding, making it a job you can often tackle yourself with the right tools. This converter interchanges with OE part numbers 18 40 7 514 504 and 18 40 7 508 760.
