Active Sound System

The Maxhaust Active Sound System simulates amazingly realistic sounding engine and futuristic e-sounds via the vehicle’s characteristics, such as engine speed and load.
Diesel, gasoline engine or electric car? With our set a sonorous, rich exhaust sound can also be retrofitted to your vehicle!

The Technology


The interface between vehicle, sound module and app.
Via the CAN-BUS of your vehicle, the Soundbooster reads all relevant data such as speed, accelerator pedal position, load, etc., processes them in real time and passes them on to the sound module.

The vehicle buttons are also processed and depending on the vehicle type, the Soundbooster enables control via the buttons such as cruise control, ESP or if available also via the driving profiles such as Comfort, Eco, Sport.

Connected via Bluetooth Low Energy (BLE) you manage all sounds and their numerous settings via our unique app. Since you are not allowed to use a smartphone while driving, you can save these settings in profiles on the Soundbooster and then control them via the vehicle buttons from your car without having to touch your smartphone.
The Perfect Integration.

Different sounds in one module

Our sound module, made for more! More power, more sounds, more possibilities.
Using a highly complex algorithm and the latest DSP technology, the processor handles our specifically developed sounds. Our engineers develop realistic sounds from real recordings of the best engines in the world.

Clear reproduction through 4 speaker channels guarantee a rich, voluminous and unique sound experience. Misfires are reproduced deafeningly real and give you a feeling that you will not want to miss.

...loud, louder, MAXHAUST

More volume

Discreet or would you like a little more?
Different speakers for different needs.
The speaker (actuator) included in the complete set is housed in a steel cabinet and provides a decent rich sound that can be easily adjusted above the 100dB limit if necessary.

You want more? Then simply choose the additional actuator that suits you from 3 optional speakers.

The optional second Deep speaker provides more volume and a better distribution of sound. Comparable to a mono or stereo sound, a second actuator acts for better sound characteristics.

The High speaker is a perfect addition to the set. This speaker reproduces the higher tones and adds a brutal new voice to the sounds. The misfires become extremely louder. Sound and misfires gain extreme authenticity through this actuator.

The Vibration speaker spreads sound waves through the engine hood and reduces the well-known nailing noise of diesel vehicles. Mounted on the intake of the interior ventilation, the sound waves deliver a discreet sound in the interior.

The App functions as Control Center

Other functions of the app

The app can do quite a bit more. In addition to a full diagnostics function of the system including help with errors, you can also download updates and new sounds.

Through our unique remote maintenance feature, we also have the ability to read your vehicle's CAN bus data in real time through the app, allowing us to troubleshoot or add new vehicles in the software

Vehicle integration

Why install buttons when your car already has them? Why use a remote control when your car is the remote control.

Since the beginning of the Active Sound development it was our ambition to integrate the system perfectly into your car.

Through the app, you can create different driving profiles and assign them to specific buttons in the car.
For example, depending on the car’s equipment, you can activate and deactivate your sound via the CANCEL button on the cruise control. It is also possible to change profiles via the ESP button without losing the function of these buttons.

No restrictions. Full control! Even while driving, safe and fast.


Do it yourself or have it done.
We help you with your decision and are always available with advice and support.
Depending on the vehicle the speakers are installed either in the trunk or underneath the vehicle. Depending on how much space is available in your car.

There will be either welding work or drilling to lead the sound tube out of the cars interior.

The electrical system is very easy to connect. Besides power and ground, only two cables are connected to the CAN-BUS. Assembly at our factory

Electric or Hybrid

The signs of the future are set and we are also moving with the times. Our software supports both fully electric and hybrid vehicles.

For the engine sounds, we simulate a synthetic RPM and gearshifts based on speed and accelerator pedal position. With these values we then generate an authentic engine sound that gives you the driving experience of a combustion engine.

Road safety also plays a very important role, as the first electric vehicles had no sound at all and the newer ones usually only have a quiet whirring sound. In traffic, these vehicles are little or not noticed and therefore pose a very high risk of accidents for pedestrians and cyclists.

Quality Made in Germany

We emphasize on details and they are reflected in all our products, in the software, in the app and in our customer support.
