THOR Level 1 is the ideal introduction to the THOR active sound system, combining the lightweight STORM loudspeaker with the intelligent THOR ECU control unit.

The STORM speaker produces a deep, smooth exhaust character suitable for everyday driving, with selectable sound profiles controlled through the THOR mobile app. Rather than modifying the vehicle's factory exhaust, THOR generates its sound electronically through an externally mounted loudspeaker.

Level 1 is designed for drivers who want the core THOR experience in a simple single-speaker configuration. The system can also be expanded later with additional THOR components and software features.

Optional THOR ECHO Upgrade

THOR ECHO can be added to Level 1 as an optional high-frequency speaker. While STORM provides the main body and depth of the exhaust sound, ECHO adds higher-frequency detail, making the overall sound brighter, more expressive and more noticeable at higher engine speeds.

THOR offers Level 1 both with and without ECHO. On our store, ECHO is available as an optional add-on to the Level 1 bundle, allowing you to choose the standard system or the enhanced STORM + ECHO configuration without purchasing a separate package.

Upgrade PRO is not included with Level 1. PRO can be activated separately through the THOR platform to unlock the extended sound library, additional sound profiles and further app functionality.
