MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 5411519 for Mercedes-Benz S430 ('04-’05) - a direct-fit replacement designed to restore emissions control and keep the check engine light off. This unit is built to match OE fit and function for 2004-2005 S430 and compatible S500 applications.
Manufactured by MagnaFlow, this direct-fit converter features a spun-body design and free-flowing mandrel-bent tubing to retain factory flow dynamics and fuel economy. MagnaFlow uses modern 3D scanning in development to replicate OE geometry, and the single laser fusion weld reduces leak potential. Constructed with corrosion-resistant stainless tubing and supplied with necessary gaskets and hardware, the converter installs without cutting or welding on compatible models. It is designed to meet California Air Resources Board requirements for the listed vehicles; installation must follow the converter’s CARB Executive Order details for EO/EFN applicability.
