With the valves open, exhaust gas flows more freely without passing through the muffler; with the valves closed, the system retains back pressure at low RPM to help maintain torque. Per Armytrix, in OFF mode the valves open automatically as a safety precaution when 4500 RPM or 0.8 bar of turbo pressure is reached. The Armytrix app connects to the OBDII device via Bluetooth and can also display real-time values such as engine speed, vehicle speed and fuel.
