Mercedes-Benz S500 Catalytic Converter - Magnaflow - Direct Fit - `04-`05. This MagnaFlow direct-fit catalytic converter replaces the factory unit on 2004-2005 S500 models, offering CARB-compliant emissions performance with a straightforward bolt-in installation.
Engineered to match OE fit and flow characteristics, this converter uses a spun-body design and mandrel-bent tubing to retain factory exhaust geometry. MagnaFlow’s R&D uses precise metrology to ensure the part fits like the original equipment, and a single laser fusion weld reduces the chance of leaks. The compact, low-mass core aids thermal efficiency while the highly corrosion-resistant stainless steel construction improves durability. Hardware and gaskets are included for an easier swap; no cutting or welding required. This unit interchanges with common OE numbers for the 2004–2005 S500 and compatible S430 applications and is tested for use in CARB-regulated states when the converter’s EO/EFN applies.
