Thanks to this “plug and play” external unit with remote control, you take control from the car's control unit and finally become the master of the valves in your exhaust system. It doesn't matter whether you have a stock exhaust system, a REMUS system, or another performance system. The exhaust valves are always controlled as standard via the on-board computer according to the set mode. The fundamental problem is that even if you set the highest sport mode via the on-board computer, it doesn't automatically mean that the valves will "listen" to you and open to 100%. It depends on the specific vehicle model (their control algorithm always differs), but it almost always applies that full opening only occurs with a warm engine, under load, and from certain RPMs! In other words, you only get the best sound from the exhaust in a narrow spectrum of car use. And that's a shame. Likewise, even in the lowest car mode, there is often a desire or need to enjoy the sound to the fullest. Only with our external unit can you fully open the valves in the exhaust at any time, or completely close them if necessary, or switch back to serial mode, and the fourth option is to open the valves to 50%. Installation is absolutely simple and can be done by any service centre, or a skilled owner can handle it at home even without tools. For most vehicles, this involves simply 'bridging' the wiring leading to the electric motor(s) that control the exhaust valves. For other vehicles, the principle of bridging the electrical circuit is implemented in a box under the dashboard, again in a 'plug and play' manner. The driver then controls the valves using a wireless controller in 4 modes, as described above. The controller is already paired with the control unit and no calibration or further settings are required. Everything is simply 'plug and play'. Given the absolutely essential benefit of improved sound (extracting the maximum from the exhaust system), purchasing this external control is simply an automatic investment.
