Magnaflow 08-10 BMW 528i 3.0L Direct Fit Converter

If you're working on your 2008-2011 BMW 528i and need to replace the catalytic converter, this direct-fit unit from Magnaflow is a solid option. It's designed to keep your check engine light off and ensure your emissions system is functioning correctly, especially if you're in a state with strict CARB regulations. Magnaflow put a lot of effort into making sure this converter fits just like the original, using 3D scanning during their research and development to replicate the factory fit and function.

What sets this converter apart is its construction and design. It features free-flowing, mandrel-bent tubing that helps maintain smooth exhaust flow for optimal performance and fuel economy, similar to the factory setup. The body is made from highly corrosion-resistant stainless steel, and the single laser fusion weld is designed to greatly reduce the chance of leaks. Its compact, low-mass design also helps with thermal efficiency. Plus, it comes with the necessary gaskets and hardware, so you won't have to reuse old, corroded parts during installation, making the job much smoother. This converter has undergone extra testing to meet California Air Resource Board requirements, making it legal for use in California and other CARB-restricted states.

This Magnaflow converter is designed to be a direct replacement, meaning no cutting or welding is required for installation, provided you have the proper tools. It interchanges with several original equipment part numbers, including 18 30 7 541 848 and 18 30 7 541 849, giving you confidence in its compatibility.
