MagnaFlow 07-13 BMW 328i 3.0L L6 California Catalytic Converter Direct Fit

If you're dealing with a check engine light on your BMW 3 Series, specifically a 2006 325i, 325xi, 330i, 330xi, or a 2007-2013 328i, 328xi, or 328i xDrive, this MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter is what you need. This part is designed to replace your original converter, ensuring your vehicle continues to meet strict emissions requirements, especially in California and other CARB-restricted states. It's built to keep that check engine light off and your exhaust system functioning correctly.

MagnaFlow puts a lot of thought into how these converters are made. They use free-flowing, mandrel-bent tubing, which helps maintain smooth exhaust flow for better efficiency. The construction is from high-strength 409 stainless steel, known for resisting corrosion and lasting a long time. They even use 3D scanning during development to make sure the fit and function are just like the original equipment. The single laser fusion weld is a key detail; it's done by replicating the OE design and greatly reduces the chance of leaks. Plus, its compact, low-mass design helps with thermal efficiency.

What's really helpful is that this is a direct-fit converter. That means no cutting or welding is required for installation, making it a job you can often do yourself with the right tools. MagnaFlow also includes the essential gaskets and hardware you'll need to get it installed properly. This converter is specifically designed to meet or exceed California Air Resource Board (CARB) requirements, and it's undergone extra testing to ensure it's legal for use in California and other states with similar emissions rules.
