Milltek Valved Rear Silencers - Mercedes C63 W205 Saloon - SSXMZ120

Milltek Rear Silencers with Active Valve Control directly replace the OE rear silencer on non-GPF Mercedes-AMG C63 and C63S W205 sedans, delivering a freer-flowing design that sharpens throttle response and refines the exhaust note without modification.

Constructed from T304L stainless steel and hand-finished for durability, these silencers feature Milltek Active Valve Control-engineered for vehicles without factory sports exhaust. The valved system allows driver-selectable tone character: closed for civilized cruising, open for full-throttle dynamics. EC Approved for street use.

• Mercedes-AMG C63 W205 Saloon (non-GPF models)
• Mercedes-AMG C63S W205 Saloon (non-GPF models)
• Direct factory fitment; uses OEM hangers and mounting points
• No modification required

Every system dyno-tested and decibel-validated to deliver both measurable power gains and engineered sound character-not volume for its own sake.
