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, but the system remains mellow 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 approved, a real advantage for driving with peace of mind and passing the technical inspection.
• Fitting: the system uses the factory mounting points. A repair shop equipped for the job usually fits it in one to two hours.
