Remus Sound Control

Enables drivers to adjust the sound of their sportexhaust systems via valve(s) which are operated per remote control or via the Sound Control App for iPhone and Android

The valve(s), are positioned pending the configuration of the exhaust, at either the inlet or at outlet side and are operated by OEM quality electronic actuators. The actuators are mounted on precise laser cut brackets. There are 4 pre-programmed valve positions offering the possibility to adjust the sound between “fully closed” and “fully opened” along with 10% and 50% open positions.

When the valve(s) are fully opened, not only the deep REMUS RACING sound is released, but also a gain in torque and power is noticeable due to the remarkable reduction of backpressure. As usual, all REMUS sportexhaust systems, including the valve mechanisms and brackets are made using only the finest stainless steel.


  • Electronically controlled valve system
  • 4 pre-set valve positions
  • Individual adjustable sound
  • Operated via remote control
  • Valve mechanisms & brackets made from stainless steel
  • Perfect fitment and easy installation

The REMUS Sound Control App

The communication between an Android or IOS smartphone and the sophisticated REMUS Sound Control electronics is via a Bluetooth connection. After basic calibration, which also takes maximum RPM into account, it is possible to operate the valve(s) in either manual or automatic mode.


Manual mode

Regardless of the engine speed, the position of the valve can be user-defined and adjusted via four buttons. The position of the valve, which is applied when the respective button is pressed, can be individually pre-set from closed to 100% open.

Automatic mode

It is possible to divide the entire RPM range into three separate segments. The lower and upper limits of each RPM segment are user-defined and adjustable. The position of the valve(s) within the chosen RPM segments can be individually pre-set from closed to 100% open. In automatic mode, the position of the valve(s) is automatically controlled throughout the 3 predefined RPM segments and does not need any further intervention by the user after the individual settings are applied.

For trouble-free usage of the REMUS Sound Controller App, connect the OBD2 plug and install the sound controller properly!

To locate the position to install the OBD2 plug, refer to your car’s manual or contact a specialist workshop! The REMUS Sound Control App will not function when the bleutooth button is connected!

The REMUS Sound Control App can be paired with various cars and sound controllers, but not at the same time! Note that the valve is always in the last chosen position when your car is started.
