Our most frequently asked questions

• Drone on the motorway? This is the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, while the system stays well-mannered at steady cruising speed, ideal for everyday driving.
• Fitting: the system uses the factory mounting points. A repair shop with the right equipment typically fits it in one to two hours.
