Most frequently asked questions

• Highway drone? It is the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, while the system 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 on startup or in comfort mode, fully open in sport mode.
• Installation: installation requires cutting the factory exhaust. We recommend having it fitted by a professional.

What customers mention most often in feedback: the fitment quality and a deep bass sound, present but never harsh. This is the Milltek Sport signature, from the British specialist in stainless steel exhausts.
