MagnaFlow Conv DF BMW 80 88

When it's time to replace the catalytic converter on your 1985-1988 BMW 535i or 1985-1987 BMW 635CSi, this direct-fit unit from Magnaflow is a solid option. You'll get the converter itself, along with a Torca clamp, a donut gasket, and three flange gaskets to help ensure a leak-free installation. This converter is designed to meet Federal emissions requirements set by the EPA, helping to keep your check engine light off and your vehicle compliant.

Magnaflow builds this converter with free-flowing, mandrel-bent tubing to eliminate restrictions and maintain factory performance and fuel efficiency. The construction uses 16-gauge 409 stainless steel tubing for excellent corrosion resistance, and the welds are durable 308 stainless steel. They use advanced 3D scanning during their research and development to ensure the part fits and functions just like the original equipment. The single laser fusion weld is designed to reduce the chance of leaks, and its compact, low-mass design also helps with thermal efficiency.

This is a direct-fit unit, meaning no cutting or welding is required for installation, making it a job you can often tackle yourself with the right tools. Just be aware that this converter is not CARB approved and cannot be shipped to California.
