Product Details

If you're working on a 2004 or 2005 BMW 545i, this direct-fit catalytic converter from Magnaflow is designed to get your exhaust system back to proper working order. It's built to keep your check engine light off and ensure your vehicle meets Federal emissions standards set by the EPA. This is the passenger side converter for your specific application.

Magnaflow builds this converter using highly corrosion-resistant stainless steel for the tubing and a durable stainless steel body. The tubing is mandrel-bent to allow for free-flowing exhaust gases, which helps maintain factory performance and fuel efficiency. They've replicated the original equipment's spun body design, and the single laser fusion weld is designed to greatly reduce the chance of leaks. This compact, low-mass design also helps with thermal efficiency. Magnaflow uses 3D scanning during their research and development to ensure this part fits and functions just like the original equipment.

Installation is made simpler because this converter is designed as a direct fit, meaning no cutting or welding is required. Magnaflow includes the necessary gaskets and hardware, so you won't have to reuse old, corroded factory parts. This converter complies with legal standards for OBDII Federally registered vehicles with Federal/EPA Emission systems.
