Frequently asked questions

• Drone on the motorway? It is the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, while the exhaust remains unobtrusive at steady speed, ideal for everyday driving.
• Fitting: the system uses the original mounting points. A workshop typically fits it in one to two hours.
