Full sound control from your smartphone

The Thunder active exhaust system gives you a unique opportunity — to control your car's sound exactly the way you want, directly from your mobile phone. No additional remote controls, no complicated settings — just a free app and Bluetooth.

The dbplus app is available for all device types:

• iOS (Apple): iPhone, iPad — download it from the App Store
• Android: all Android-based devices — the app installation file will be provided after purchasing the kit

The app is completely free and requires no subscriptions or in-app purchases.

Initial setup: how it all works

After installing the system and making the first connection, a few simple steps are required for setup:

1. Download the dbplus app to your phone
2. Turn on Bluetooth on your phone and pair it with the Thunder system
3. Open the app and tap the "i" icon (info) in the top right corner
4. Select the make, model, and year of your car from the list
5. Click the Download button at the bottom of the screen

After this, individual parameters optimised specifically for your car will be downloaded. These parameters will be saved in the system's electronic control unit.

Once the settings are loaded, various exhaust sound presets of naturally aspirated petrol engines will become available in the app. You will be able to choose between the sound of a V8, V12, sporty V6, and other configurations.

The dbplus app interface

The app features an intuitive interface that requires no special knowledge. Here is what the main control screens look like:

Detailed sound settings

The dbplus app offers extensive options for fine-tuning your car's sound:

1. Engine start setting

The parameter with the red slider allows you to control the rpm behaviour when starting the engine:

• Lower position: The rpm remains at idle level — a calm, gentle start
• Upper position: The rpm at start first "jumps up" (like on sports cars) and then returns to the idle zone — a spectacular appearance

2. Idle sound adjustment

You can adjust the sound character at idle:

• High idle rpm — a more aggressive sound when stationary
• Low idle rpm — a calm, subdued sound

3. Full sound mute button

The app features a special "B" button that mutes the exhaust sound down to complete silence. This is the ideal solution for situations where you want to be unobtrusive or not disturb others — for example, at night when entering a courtyard or residential complex.

Saving personal configurations

The app allows you to save up to 4 individual sound configurations. This means you can create several profiles for different situations:

• "Sport" profile: Maximum aggressive sound, spectacular start
• "City" profile: Moderate sound for everyday driving
• "Night" profile: Subdued sound or complete silence
• "Highway" profile: Optimal balance for long trips

You can switch between profiles at any time directly from the app.

Intelligent memory

The Thunder system remembers the last used settings. The car always starts with the parameters that were active at the time the engine was last turned off. This means:

• If you turned off the engine in "Sport" mode — it will roar sportily again on the next start
• If you muted the sound with the "B" button before parking — the car will start in quiet mode

For those who want the car to always start without sound, simply create the appropriate configuration and activate it before turning off the engine. The system will remember this choice.
