Fabspeed Mercedes-Benz AMG GT/GTR/GTS Sport Cat Downpipes (2015-2021)


Constructed from T304L high-quality stainless steel, Fabspeed Motorsport AMG GT/GTR/GTS Sport Catalytic Converters offer premier quality catalysts by utilizing HJS Germany Tri-Metallic 200 cell catalysts. We perfectly match the sound expected of the AMG GT cars by dramatically improving sound and power throughout the RPM range offering a much-needed solution to the boring factory exhaust. Using only certified high-performance HJS components imported directly from Germany, our system eliminates all risk for black market, grey market, or counterfeit HJS catalytic converters from other companies. Increase the muscular twin-turbocharged Mercedes Bi-Turbo sound and reduce backpressure allowing for much quicker turbocharger spooling and transient turbo response. Fabspeed sport cats replace the restrictive OEM 800 cell catalytic converters with HJS Emissions Technology catalysts guaranteeing O CEL (Check Engine Light) (on US cars only).
