Active Sound Installation on Audi Q7 3.0 TDI – THOR Sound Booster

Watch how this Audi Q7 3.0 TDI gets transformed with a THOR Active Sound System — a high-tech solution that adds deep, aggressive exhaust notes to diesel vehicles without any physical exhaust modification.

🔊 What Is Active Sound?

THOR’s Active Sound technology uses an electronic sound booster mounted near the exhaust to simulate the sound of powerful petrol engines such as V8s and V10s. Connected via CAN-BUS, the system adjusts tone and intensity in real time, based on throttle input and RPM.

📱 Mobile App Control

The system is fully controlled via smartphone (iOS & Android), allowing the driver to:

Switch between sound profiles (Comfort, Sport, Race, etc.)
Increase or decrease volume
Automatically change sound based on driving mode
Turn sound on/off anytime

🔧 Installed by ASF Tuning

This installation was completed in under 3 hours, with no permanent modifications made to the vehicle. The THOR unit was calibrated and tested for optimal performance. System is removable and transferable to your next car.
