Magnaflow Conv DF 2003 ML350 3.7L Underbody

If you're working on a 2003-2005 Mercedes-Benz ML350 and need to replace the catalytic converter, this direct-fit unit from Magnaflow is a solid option. It's designed to help keep your check engine light off and ensure your vehicle meets federal emissions standards. This converter is built to function just like the original equipment, so you can be confident in its performance and fit.

Magnaflow uses high-strength 16-gauge 409 stainless steel for the tubing, which offers excellent resistance to corrosion and helps ensure a long service life. The tubing is mandrel-bent to maintain the original design and geometry, which helps prevent flow restrictions and keeps factory performance and fuel efficiency consistent. The single laser fusion weld is designed to minimize the possibility of leaks, and the compact, low-mass design contributes to better thermal efficiency. This converter is also designed to meet or exceed EPA requirements for OBDII federally registered vehicles.

Installation is made easier because this is a direct-fit unit, meaning no cutting or welding is required, just proper tools. Magnaflow includes a Torca Accuseal clamp, which provides a 360-degree, evenly distributed clamping force for a secure seal. Essential hardware is also included to help you avoid issues with corroded factory parts. Please note that this converter is not CARB approved and cannot be shipped to California.
