This app offers unlimited profiles to set up and configure, and each profile can be customized with different settings. The app allows you to adjust idle volume and dynamic volume separately, idle RPM, dynamic RPM, engine start sound, simulated rough idle RPM, RPM-dependent volume control, and overrun-dependent volume.

With the Maxhaust Sound Module, you can enjoy additional features such as an equalizer function, backfire/misfire, and multiple sound options from V6 to V10. The Sound Module also supports up to four speakers, which can be placed inside or outside the car for the perfect sound in any situation.

The app can be easily controlled via Bluetooth Low Energy, and profile selection can be done through the app or original car buttons. Other features include a demo mode, product customization, and remote service via the app, free software updates, no download limit when changing cars, and automatic detection of external sound modules.
