Product Details
If you're working on a 2009-2012 Mercedes-Benz GL450, GL550, or 2009-2011 ML550 and need to replace the catalytic converter, this direct-fit unit from Magnaflow is a solid option. It's designed to keep your check engine light off and meet strict emissions standards, especially if you're in California or another state with CARB regulations. Magnaflow uses advanced 3D scanning to ensure this converter matches the original equipment's fit and function, so you won't have to worry about it not lining up correctly.
This converter is built with free-flowing, mandrel-bent tubing to help maintain smooth exhaust flow, which is important for keeping your engine running efficiently. The construction uses high-strength 16-gauge 409 stainless steel tubing for good corrosion resistance and a long service life. Magnaflow also uses a single laser fusion weld, which significantly reduces the chance of exhaust leaks. The compact, low-mass design is also engineered for better thermal efficiency. Because it's a direct-fit unit, installation is made simpler as it's designed to bolt right up without needing any cutting or welding, and it includes the necessary gaskets and hardware.
This Magnaflow converter has undergone additional testing to comply with California Air Resource Board (CARB) guidelines, making it legal for use in California and other CARB-restricted states. It's a well-built replacement that aims to meet or exceed OEM performance and emissions requirements.
