Mercedes-Benz E55 AMG Catalytic Converter - Magnaflow - Direct-Fit, HM Grade - 2003–2006. This federal/EPA-compliant direct-fit converter replaces the factory unit to maintain emissions compliance and proper engine operation with a bolt-in installation.
Designed specifically for 2003–2006 Mercedes-Benz E55 AMG and the 2006 CLS55 AMG, this MagnaFlow HM Grade unit replicates OE spun-body geometry using 3D-scanned metrology for a reliable fit. The compact, low-mass design improves thermal efficiency while a single laser fusion weld reduces leak potential. Constructed with mandrel-bent tubing and high-strength 16-gauge 409 stainless steel, it resists corrosion and preserves factory exhaust flow characteristics to support performance and fuel economy. Hardware and gaskets are included so installation can be completed with common hand tools—no cutting or welding required.
