Product Details

Magnaflow is well-known for making exhaust components that flow well and last a long time. This direct-fit catalytic converter is built to keep your 2004-2005 BMW 545i running smoothly and legally. It’s designed to replace the original converter without needing any cutting or welding, making installation much simpler for you. This part is crucial for your car's emissions system, helping to convert harmful gases into less harmful ones and keeping your check engine light off.

This converter uses free-flowing, mandrel-bent tubing, which helps maintain the factory performance and fuel efficiency you expect. The construction is highly corrosion-resistant, thanks to the 16-gauge 409 stainless steel tubing and durable 308 stainless steel MIG welds. Magnaflow uses advanced 3D scanning during their research and development to ensure this converter fits just like the original equipment. The OE-style spun body design and a single laser fusion weld significantly reduce the chance of leaks, and its compact, low-mass build allows for better thermal efficiency.

To make installation as straightforward as possible, this converter comes with essential gaskets and hardware. This means you won't have to worry about reusing old, corroded factory parts or searching for compatible seals. This replacement converter is designed to meet or exceed Federal emissions requirements set by the EPA for OBDII Federally registered vehicles. Please note that this converter is not CARB approved and cannot be shipped to California.
