Frequently asked questions

• Highway drone? It is the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, while the system stays calm at steady cruising speed, ideal for everyday driving.
• Race version: the loudest in the range, built for the track and for enthusiasts who want the sensation. It is not meant for quiet long-distance trips.
• Fitting: the system uses the original mounting points. A workshop with the right equipment typically fits it in one to two hours.
