Frequently asked questions

• Highway drone? It's the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, but the system stays calm at steady cruising speed, ideal for everyday driving.
• What about the neighbors in the morning? The valves are controlled as on the original: the system stays closed and discreet on cold start or in comfort mode, and fully opens in sport mode.
• Homologation: this system is ECE / EC homologated, a real plus for driving with peace of mind and passing the contrôle technique.
• Fitting: the system uses the original mounting points. A properly equipped repair shop usually fits it in one to two hours.
