Frequently asked questions

• What about the neighbors in the morning? The valves are controlled as on the original system: the exhaust stays closed and quiet at startup or in comfort mode, and fully opens in sport mode.
• Homologation: this system is ECE / EC approved, a real advantage for driving with peace of mind and passing the contrôle technique.
• Fitting: the system uses the original mounting points. An equipped repair shop usually fits it in one to two hours.
