Magnaflow Conv DF BMW 5 99-00 Front

This Magnaflow direct-fit catalytic converter is built with a high-strength 16-gauge 409 stainless steel body and tubing, offering solid corrosion resistance for a long service life. It’s designed to keep your check engine light off and ensure your 1999-2000 BMW 528i passes emissions testing, especially in California and other CARB-restricted states. Magnaflow uses advanced 3D scanning during development to ensure this converter replicates the original equipment's fit and function precisely.

The spun body design, featuring a single laser fusion weld, greatly reduces the chance of leaks, while its compact, low-mass construction helps with thermal efficiency. Because it's a direct-fit unit, installation is straightforward with no cutting or welding required, making it a manageable job for many DIYers. You can be confident in its compliance, as it has undergone additional testing to meet California Air Resource Board (CARB) guidelines.

To make installation even easier and avoid reusing old, corroded parts, this converter comes with the necessary gaskets and hardware. This ensures a proper seal and a more reliable repair. It interchanges with several original equipment part numbers, including 11 62 7 503 673 and 11 62 1 439 859.
