Mercedes C63 AMG (W204) – Valved Exhaust System

T304 Stainless Steel • 2.75" Free-Flow • Quad AMG Tips

Overview

The M156 6.2L V8 is an all-time great—its bark is why so many choose the C63 over anything else. The Valvetronic Designs Valved Exhaust System fixes that. Built from anodized-gold T304 stainless and measuring 2.75" to a set of classic quad AMG-style tips, it delivers the raw M156 thunder on demand—and true quiet when you need it.

Sound & Control

Valves Open: Near-unrestricted flow for that signature, ferocious 6.2L tone—crisp upshifts, hard-edged growl, maximum character.
Valves Closed: Stock-like volume with zero drone, perfect for city driving, late-night returns, or low-profile cruising.
Standalone Control: Toggle loud/quiet at the touch of a key-fob remote, independent of drive modes.
