Mercedes C63 AMG Catback Exhaust | WSTN Performance (M156 W204/S204/C204)

The M156 6.2L V8 is one of the last naturally aspirated AMG engines. The factory exhaust is the ceiling, not the floor. WSTN Performance T304 stainless Valved catback exhaust for the 2008-2015 Mercedes-Benz C63 AMG. Direct-fit replacement for the factory rear system with valve control for open and closed modes, quality-checked at our Perth WA facility before dispatch worldwide. Why Upgrade? ✓ Sound on Your Terms: Valved design switches between a composed daily note with valves closed and the full 6.2L V8 character with valves open. One system, two modes. ✓ Free-Flow Design: Mandrel-bent pipework removes the factory restriction points the OEM system uses to suppress the M156's natural character. More sound, less back pressure. ✓ T304 Stainless Construction: Corrosion-resistant and dimensionally matched to the W204/S204/C204 chassis. Built to outlast the factory system. ✓ Hand Built to Order: Each system is built to your specification from Perth WA. Not sourced from warehouse stock.
