MagnaFlow Conv DF BMW 3 01-06 Rear OEM

If you're working on a BMW 3 Series from 2001-2006, or even a compatible X3, Z3, or Z4 model from those years, this MagnaFlow Direct-Fit Catalytic Converter is designed to get your emissions system back in order. This part is crucial for keeping your check engine light off and ensuring your vehicle meets federal emissions standards. It's built to replace the original equipment directly, meaning you won't have to cut or weld to get it installed, making the job much simpler.

MagnaFlow uses high-strength 16-gauge 409 stainless steel tubing for the body, which offers excellent resistance to corrosion and helps ensure a long service life. The internal design features free-flowing, mandrel-bent tubing to maintain factory performance and fuel efficiency, while the compact, low-mass design contributes to better thermal efficiency. The converter body is constructed with durable 308 stainless steel MIG welds, and the single laser fusion weld replicates the OE spun body design to greatly reduce the chance of leaks. This converter is designed to meet or exceed federal emissions requirements set forth by the EPA for OBDII vehicles registered in states that follow federal emissions standards.

To make installation as straightforward as possible, this MagnaFlow converter comes with the necessary gaskets and hardware. This means you won't have to reuse old, corroded factory parts, which can often lead to exhaust leaks. This direct-fit converter is a solid option for restoring your BMW's emissions system to proper working order, ensuring it runs cleanly and efficiently.
