Fabspeed Sport Cat Downpipes for S213 / X290 Mercedes-AMG E 63 S & GT 63 [FS.MER.M177.SC]

Fabspeed Motorsport’s Sport Catalytic Converters for the AMG E63 Wagon and GT63 are crafted from premium T304L stainless steel and feature genuine HJS Germany Tri-Metallic 200-cell catalysts for exceptional quality and performance. Designed to significantly enhance both sound and power across the RPM range, these sport cats deliver the aggressive, signature tone expected from AMG vehicles while improving turbo spool and reducing backpressure. Only certified HJS components imported directly from Germany are used, ensuring authenticity and eliminating the risk of counterfeit or grey-market alternatives. Replacing the restrictive OEM 800-cell units, these converters also guarantee a CEL-free experience on U.S. vehicles.
