Our Most Frequently Asked Questions

• Highway drone? It is 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 factory system: closed and quiet on startup or in comfort mode, fully open in sport mode.
• Homologation: this system is ECE / EC homologated, a real plus for driving with peace of mind and passing the contrôle technique.
• Installation: the system uses the original mounting points. A workshop with the right equipment typically fits it in one to two hours.
