THOR is an electronically generated external vehicle sound system. It reads live vehicle data through CAN and uses one or more externally mounted loudspeakers to produce a responsive exhaust-style sound without replacing the vehicle's factory exhaust system.

The ECU reads supported vehicle parameters such as engine speed, throttle position and acceleration data. The selected sound is generated in real time and changes with acceleration, RPM build-up, throttle lift-off and driving style rather than operating as a simple fixed audio recording.

Choose Level 1 for the balanced STORM-based entry system, Level 2 for the deeper and more powerful THUNDER 2.0 single-speaker setup, or Level 3 for the flagship combination of THUNDER 2.0 and STORM. ECHO can be added to any level for additional high-frequency detail.

STORM is the lighter, versatile main loudspeaker and provides a balanced sound with strong mid-range presence. THUNDER 2.0 is the premium metal-housing loudspeaker and is tuned for deeper bass, stronger low-frequency output and greater sound presence.

ECHO is an additional high-frequency component. It works alongside STORM or THUNDER 2.0 to add extra upper-frequency detail, brightness and definition. It is optional on Levels 1, 2 and 3 and can also be added later to a compatible system.

Upgrade PRO unlocks the extended THOR sound library, newly released sound profiles, special and situational sounds including BOOMBOX, and additional functionality as the platform develops. Level 1 does not include PRO as standard; Levels 2 and 3 include it.

The standard Level 1 software package provides 10 core exhaust profiles. THOR's current FAQ describes the PRO library as containing more than 30 exhaust profiles plus special and situational sounds. The library continues to change as new content is released.

Yes. THOR supports remote sound-library and system-software updates through the mobile app. THOR currently states that new sound profiles are typically released every one to two months for users with Upgrade PRO.

Yes. The system can be muted completely through the THOR app. On supported vehicles, factory controls or Drive Select integration can also be configured for sound control.

THOR states that system output can range approximately from 95 to 115 dB depending on the hardware configuration, installation position and user settings. Volume is adjustable through the mobile app and should always be used in accordance with local noise requirements.

THOR is designed as a broadly compatible system for modern CAN-bus vehicles and supports a wide range of petrol, diesel, hybrid and electric cars. The manufacturer states that most supported applications are from approximately model year 2005 onwards. The correct vehicle/CAN profile is selected during setup, and compatibility should be confirmed for uncommon or newly released vehicles.

Yes. Diesel vehicles are one of the most obvious applications for active sound because THOR can create a much more expressive performance sound without changing the factory exhaust hardware.

Yes, where a compatible CAN profile is available. On EV applications THOR uses vehicle data such as speed, throttle and braking to generate sound. Compatible EV setups can also use THOR's virtual gearbox effects to simulate shifts and other performance-car transitions.

No exhaust-pipe modification is required for the THOR system itself. The acoustic units are mounted underneath the vehicle and operate independently of the original exhaust flow and emissions-control hardware.

THOR is a sound system rather than an engine-performance modification. Its CAN connection reads supported vehicle data but does not tune the engine or command the drivetrain. It does not increase engine output or change the factory exhaust system.

THOR does not require removal or modification of the catalytic converter, diesel particulate filter or other factory emissions hardware. It changes the vehicle's external sound rather than its exhaust-gas treatment.

THOR quotes an average installation time of around 5–8 hours. The actual time depends on the vehicle, speaker mounting location, electrical access and whether additional CAN-profile work is required.

THOR states that self-installation is possible for people experienced with automotive electronics, but recommends a specialist installation centre. The system requires correct CAN and power connections together with secure underbody mounting. Products carrying our professional-installation warning must be professionally installed to protect the applicable warranty.

Yes. THOR is modular and can be removed and installed in another compatible vehicle. The wiring or mounting arrangement may need to change, and the correct CAN profile needs to be selected for the new vehicle.

Yes. Level 1 can be expanded with THUNDER 2.0, ECHO and Upgrade PRO. Level 2 can add STORM and ECHO, while Level 3 can add ECHO. The ECU supports up to two main THOR loudspeakers plus one ECHO module in the current maximum configuration.

The external acoustic components are designed for underbody automotive use and exposure to normal road conditions, while the ECU is installed inside the vehicle. Correct mounting and wiring remain important for long-term reliability.

THOR recommends switching the system off if the acoustic units may become partially or fully submerged. A speaker diaphragm operating in water is subjected to much higher mechanical load than it is in air. Once clear of the water, reactivate the system at low volume before gradually increasing it.

On supported vehicles, THOR can associate sound presets with factory drive modes such as Comfort and Sport. Changing the vehicle's drive mode can then change, mute or activate the corresponding THOR profile without needing to use the phone each time.

Check that Bluetooth is enabled, the vehicle and THOR system are powered, and the ECU is not already connected to another phone. Restart the app or phone and try again. If the device still cannot be detected, check the system connections and contact technical support.

THOR does not require the factory exhaust system to be replaced, but vehicle-noise rules still apply. Requirements and permitted noise levels vary by location, so the system should be operated at an appropriate volume and in accordance with the rules applying where the vehicle is driven. THOR can be reduced in volume or switched off completely when required.
