Overview

The Mercedes-AMG exhaust valve module takes over control of the factory exhaust valves and is operated directly from a phone app — no dashboard button and no factory logic needed.

Valve opening is adjustable in four steps — 0 / 30 / 50 / 100. Keep it quiet when you want, open it up when you don't, and switch at any time.

Startup roar: the valve opens automatically the moment the engine starts for a more direct cold-start note.

The app is available in both Chinese and English with a clean interface — connect and operate.

Three selectable control modes — manual, protocol and factory — plus RPM-based control: stay quiet at low rpm and open up automatically at higher rpm, so you don't have to switch manually between daily driving and spirited runs.

The factory motor does not need to be sent out for coding or bypassing, saving that programming and wiring cost.

Fitment: Mercedes-AMG A35 / CLA45 / GLC43 / CLE53 / C63 / AMG GT / G63.
