MagnaFlow 08-10 BMW 535i California Catalytic Converter Direct Fit 2.5in Pipe Diameter

If you're working on a 2008-2010 BMW 535i or 535xi and need to replace the catalytic converter, this MagnaFlow California Grade CARB Compliant Direct-Fit unit is a solid option. It's designed specifically to meet or exceed California Air Resource Board requirements, meaning it's legal for use in California and other states with strict emissions standards. This is crucial for keeping your check engine light off and ensuring your car passes emissions tests.

MagnaFlow builds this converter with free-flowing, mandrel-bent tubing and uses highly corrosion-resistant stainless steel for the construction, which means it's built to last. They use advanced 3D scanning during development to make sure the fit and function are just like the original equipment your BMW came with. The design replicates the OE spun body, and the single laser fusion weld is a smart detail that greatly reduces the chance of exhaust leaks. Its compact, low-mass design also helps with thermal efficiency.

This converter is a direct fit, so you won't need to cut or weld anything during installation, making the job much simpler with the proper tools. Essential gaskets and hardware are included in the box to help with installation. This part interchanges with OE part number 18 30 7 565 331.
