The Exhaust Valve Management Module by Shiftech

At ShifTech, we believe that every driver should have complete control of their vehicle, and that includes the sound. That's why we now offer our very own ShifTech Remote Control Exhaust Valve Controller.

As car enthusiasts, we all know that the sound of a car is an essential part of the driving experience. There's something undeniably appealing about the deep roar of an engine. But how exactly does the exhaust system control this sound? The answer lies in the exhaust valves.

Exhaust valves: How do they control sound?

Exhaust valves, also known as exhaust flaps, are mechanical devices located in the exhaust system of a car. They play a crucial role in modulating the sound produced by the vehicle, allowing drivers to control the noise level of their car. This is essential to comply with noise regulations and also to allow the sound to be customised to the driver's preferences.

In theory, the valves work quite simply. When the exhaust gas from the engine reaches the valve, it can be opened or closed, depending on various factors such as engine speed, vehicle speed and the chosen driving style.
When the valve is open, the exhaust gases flow freely through the exhaust line, creating a louder, deeper engine sound. On the other hand, when the valve is closed, the exhaust gases are redirected through resonance chambers or additional silencers that attenuate the sound, making the engine quieter.
It is the modulation of the opening and closing of these valves that creates the variations in sound we hear when we accelerate, decelerate or change driving mode. In the majority of cases, this is managed by the engine control unit (ECU), which prevents the driver from having total control of the valves as desired.

Controlling your exhaust with ShifTech

Keep total control of your exhaust system with the valve module controller by ShifTech.

this innovative device gives you the freedom to manually manage the sound of your exhaust by adjusting the opening and closing of the valves at will, regardless of engine speed, gear or mode selected. And for those times when you prefer to revert to the original mode, the automatic mode is always at hand, accessible at the click of a button on the remote control.

The installation of this module integrates perfectly with the original exhaust system without requiring any major modifications.
