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

CTS Turbo's 3" high-flow downpipes for the Mercedes-Benz W205 C63/63S put performance first. Wrapped in shielded material to keep heat in the exhaust and out of the engine bay, they let you drive longer and harder while improving spool and throttle response.

Built to last, built to fit

CAD-designed to drop perfectly into the restrictive factory catalytic-converter location and manufactured from cast T304 stainless steel, hand TIG-welded and back-purged for years of reliable service. Another benefit: an improved sound that is louder, deeper, mean and wonderful at once.
