Most frequently asked questions

• Highway drone? It is the number one concern on forums. This version keeps a resonator: the tone stays full under acceleration, while the exhaust remains unobtrusive at steady cruising speed, ideal for daily driving.
• And 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 exhaust is homologated (ECE / EC), a real plus for driving with peace of mind and passing the French contrôle technique inspection.
• Fitting: the exhaust uses the factory mounting points. A workshop typically fits it in one to two hours.
