Shadow Electronic Exhaust Valve Controller II

The Shadow Electronic Exhaust Valve Controller II – Modified Version is specifically designed for aftermarket exhaust systems.
It offers three operating modes: ON, OFF, and AUTO.

Compatible with genuine factory electronic valve motors found in brands such as BENZ, BMW, and VAG, as well as aftermarket vacuum valve solenoids.
As long as a 12V power source is available, the system can be installed on virtually any vehicle.

In AUTO mode, the valve operation can be customized via OBDII connection, allowing users to set automatic open/close preferences based on driving behavior. Manual control is also available through a mobile device, remote control, or the main control unit.

While enhancing vehicle performance, it also delivers an exhilarating auditory experience with instant changes in exhaust sound.
With the Shadow Electronic Exhaust Valve Controller II, your vehicle can remain discreet and quiet—or instantly unleash its aggressive tone. That’s the essence of its design.

Equipped with Bluetooth 4.2 connectivity and a 32-bit MCU processor for faster, more stable signal communication. It features an automotive-grade dedicated wiring harness that minimizes signal interference and enables more precise motor control, effectively preventing potential valve malfunctions.

The package includes a specialized wiring kit compatible with OEM electronic exhaust valve motors of BMW, BENZ, and VAG. Regardless of vehicle model, as long as it supports an OBD2 connection, it can be directly installed and used with the Auto function.

Set the valve opening timing in Auto mode via the app and enjoy a performance exhaust experience beyond the factory setup.

The redesigned remote control keeps you in command with an all-new structure that fuses a sleek aluminum alloy frame and soft-touch silicone buttons—bringing both tactile satisfaction and a premium feel. Every press is deliberate. Every response, visible.

Powered by a 32-bit MCU and Bluetooth 4.2 chipset, the SHADOW Electronic Exhaust Valve Controller II ditches outdated analog signals for advanced pulse transmission. The result? Sharper response, cleaner signals, and immunity to power surges.
