MagnaFlow Conv DF 04-05 BMW 530i 3.0L Rear Ma

When your check engine light comes on for emissions issues, you need a reliable replacement like this MagnaFlow Direct-Fit Catalytic Converter. This unit is built to keep your 2004 or 2005 BMW 525i or 530i compliant with Federal and EPA emissions standards, ensuring your vehicle runs cleanly and legally. It's designed as a direct replacement, meaning it bolts right up to your existing exhaust system without needing any cutting or welding, making installation much simpler.

MagnaFlow uses high-strength 16-gauge 409 stainless steel for the tubing, which is known for resisting corrosion and lasting a long time. The converter body itself is constructed with a compact, low-mass design that helps with thermal efficiency. They also replicate the original equipment's spun body design, using a single laser fusion weld that significantly reduces the chance of leaks. Inside, the free-flowing mandrel-bent tubing helps maintain the factory performance and fuel efficiency you expect. MagnaFlow uses advanced 3D scanning during their research and development to ensure this converter fits and functions just like the original part.

To make installation as straightforward as possible, this catalytic converter comes with the necessary gaskets and hardware. This means you won't have to worry about reusing old, potentially corroded parts or making a separate trip to the auto parts store. This converter is designed to meet or exceed Federal emissions requirements for OBDII Federally registered vehicles, but please note it is not CARB approved and cannot be shipped to California.
