Magnaflow 08-13 128i 3 L Underbody Direct Fit Converter

This is the Magnaflow Direct-Fit Catalytic Converter, part number 21-990, specifically made for the 2008 through 2013 BMW 128i with the 3.0L engine. If your check engine light is on due to emissions issues, or if your original converter is failing, this part is designed to get your BMW back to running cleanly and efficiently, meeting Federal emissions standards.

Magnaflow builds this converter with 16-gauge 409 stainless steel tubing, which is well-built to resist corrosion and last a long time. The tubing is mandrel-bent to keep the factory-like design and geometry, ensuring it flows like the original equipment. They use 308 stainless steel for the Mig welds, which are strong and help prevent leaks. The compact design also helps with thermal efficiency. Magnaflow uses advanced 3D scanning during their research and development to make sure this converter fits precisely like the factory part, so you won't need to cut or weld anything during installation. It comes with a Torca AccuSeal clamp, which provides a full 360-degree clamp for a secure seal.

This converter is designed to meet EPA Federal emissions requirements for OBDII Federally registered vehicles. It's important to note that this converter is not CARB approved and cannot be shipped to California. You'll also find the necessary gaskets and hardware included to simplify the installation process.
