CTS TURBO MERCEDES-BENZ AMG W205/M177 C63/63S DOWNPIPES HIGH-FLOW CATS

CTS Turbo's high-flow catalytic downpipes are engineered specifically for the Mercedes-Benz W205 C63 and C63S models fitted with the M177 twin-turbo V8. These downpipes replace the restrictive factory components to significantly reduce exhaust backpressure whilst maintaining emissions compliance through high-flow catalytic converters. The result is improved throttle response, reduced heat soak and a more aggressive exhaust note. Precision-manufactured for direct bolt-on fitment to 2015-2021 W205 chassis C63 variants, these downpipes are an essential upgrade for tuned AMG applications seeking maximum performance gains without sacrificing street legality.
