Product Details

Starting with its construction, this MagnaFlow catalytic converter uses 16-gauge 409 stainless steel tubing, which is known for being highly resistant to corrosion and built to last. This is a direct-fit unit, meaning it's designed to bolt right up to your factory exhaust system without any cutting or welding. MagnaFlow uses advanced 3D scanning during their research and development to ensure the converter replicates the original equipment's fit and function, so you can be confident it will work correctly on your 2004-2005 BMW 545i, 645Ci, 745i, or 745Li.

The spun body design, similar to the original equipment, is sealed with a single laser fusion weld. This method greatly reduces the chance of exhaust leaks. Its compact, low-mass design also helps with thermal efficiency. This converter is built to meet or exceed Federal emissions requirements set by the EPA, keeping your check engine light off and your vehicle compliant with OBDII Federal Emission systems.

To make installation as straightforward as possible, this converter comes with all the necessary hardware, including flange gaskets, bolts, and nuts. This means you won't have to struggle with corroded factory parts. It's designed to interchange with OE part numbers 18 40 7 522 555 and 18 40 7 522 571.
