The MagnaFlow California direct-fit catalytic converter for 2009–2012 Mercedes‑Benz GL450 4.6L replaces the OE unit while meeting CARB requirements. It uses mandrel-bent tubing and corrosion‑resistant stainless construction to preserve exhaust flow and fuel economy. Precision 3D-scanned OE geometry, a single laser fusion weld and included gaskets/hardware simplify installation with no cutting or welding required.
