Magnaflow 08-10 BMW 535i 3.0L Direct Fit Converter

If your 2008-2010 BMW 535i is showing a check engine light related to emissions, it might be time to replace the catalytic converter. This direct-fit converter from Magnaflow is designed specifically for your 535i, including xDrive and xi models, and meets California Air Resources Board (CARB) requirements. This means it's legal for installation in California and other states with strict emissions standards, helping you keep that check engine light off and your car running cleanly.

Magnaflow builds this converter using free-flowing, mandrel-bent tubing made from high-strength 16-gauge 409 stainless steel, which resists corrosion and should last a long time. They use advanced 3D scanning during development to ensure it fits just like the original equipment, making installation straightforward. The single laser fusion weld is designed to prevent leaks, and its compact, low-mass design helps with thermal efficiency. You won't need to cut or weld anything; it bolts right up, and it even comes with a flange gasket to help ensure a good seal.

This converter is built to meet or exceed CARB requirements, and Magnaflow has tested it thoroughly to ensure compliance. It interchanges with OE part numbers 18 30 7 565 684 and 18 30 7 565 688. You'll also find durable 308 stainless steel MIG welds holding it all together.
