Product Details

This is the Magnaflow Standard Grade Direct-Fit Catalytic Converter for your 1981-1984 BMW 633CSi. If your check engine light is on due to emissions issues, this part is designed to get your car running cleanly again and keep that light off. It's built to meet or exceed Federal emissions requirements set forth by the EPA, making it a solid choice for keeping your BMW compliant.

Magnaflow puts a lot of effort into making sure these converters fit right the first time. They use advanced 3D scanning during their design process to replicate the original equipment's fit and function. The tubing is mandrel-bent to ensure smooth exhaust flow, which helps maintain factory performance and fuel efficiency. Construction is from high-strength 16-gauge 409 stainless steel for excellent corrosion resistance, and the single laser fusion weld is designed to greatly reduce the chance of leaks. The compact, low-mass design also helps with thermal efficiency.

Installation is made easier because this converter is designed as a direct fit, meaning no cutting or welding is required if you have the proper tools. Magnaflow includes two flange gaskets, one Torca clamp, and one donut gasket to help you get a good seal during installation. Please note that this converter is not CARB approved and cannot be shipped to California.
