Our most frequently asked questions

• Highway drone? It's the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, while the system remains unobtrusive at steady cruising speed, ideal for everyday driving.
• Fitting: the system uses the original mounting points. An equipped repair shop typically fits it in one to two hours.
