Our 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 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 at startup or in comfort mode, fully open in sport mode.
• Homologation: this system is ECE / EC homologated, a real advantage for driving with peace of mind and passing the French contrôle technique.
• Installation: the system uses the original mounting points. A well-equipped repair shop usually fits it in one to two hours.

Why choose Milltek Sport?

Owner feedback most often mentions the fit quality and a deep tone that is present but never shrill. This is the Milltek Sport signature, from the British manufacturer specializing in stainless steel exhausts.
