MagnaFlow Conv DF 97-98 BMW 540I / 97-98 740I / 96-98 740IL 4.4L D/S

This Magnaflow direct-fit catalytic converter is what you get when you need to replace the original on your 1996-1998 BMW 740iL, 1997-1998 740i, 1997-1998 540i, or 2016-2019 Cadillac ATS. It's designed to keep your check engine light off and ensure your vehicle meets Federal emissions requirements. Magnaflow builds these to be a direct replacement, meaning no cutting or welding is needed for installation, just proper tools and a straightforward bolt-on process.

You'll find that Magnaflow uses a strong 16-gauge 409 stainless steel for the tubing, which is great for resisting corrosion and ensuring it lasts. The converter body itself is a spun design, similar to the original equipment, and it's sealed with a single laser fusion weld. This construction helps reduce the chance of leaks and the compact, low-mass design allows for better thermal efficiency. The mandrel-bent tubing is also designed to maintain the original flow dynamics, so you can expect your vehicle to perform as it should.

To make installation as smooth as possible, this converter comes with the necessary gaskets and hardware. This means you won't have to worry about reusing old, corroded parts or dealing with a leaky seal. It's built to meet or exceed EPA emissions standards for OBDII federally registered vehicles.
