Mercedes-AMG C63 Valved Cat-Back Exhaust System

Developed specifically for the Mercedes-AMG C63 W205, this valved cat-back exhaust system enhances both sound and presence while maintaining OEM-level fitment. Constructed from high-grade stainless steel, it features a quad exit layout and integrated valvetronic technology for full sound adjustability.

The system includes complete cat-back pipework, precision clamps and fittings, valve actuators (where applicable) and a remote-control module for seamless operation. Switch effortlessly between a refined cruising tone and a fully open, aggressive AMG sound profile.

Each system is hand-built to order using precision welding techniques. Production time is up to four weeks from payment confirmation, with dispatch the next working day once completed.

As a bespoke, made-to-order product, returns are accepted only in the event of confirmed manufacturing defects.
