Most frequently asked questions

• Highway drone? It's the top concern on forums. This version keeps a resonator: the tone stays full under acceleration, but the exhaust stays calm at steady cruising speed, ideal for daily driving.
• What about the neighbors in the morning? The valves are controlled as on the factory system: closed and discreet at startup or in comfort mode, fully open in sport mode.
• Installation: fitting requires cutting the factory exhaust. We recommend having it fitted by a professional.

Why choose Milltek Sport?

Feedback from users most often points to fit quality and a deep tone that is present but never harsh. This is the Milltek Sport signature, from the British manufacturer specializing in stainless steel exhausts.
