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.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, using mandrel-bent tubing to preserve the inner diameter and fitment developed specifically for the vehicle. Result: a clean installation with no modifications needed, and a sound tuned to stay pleasant for everyday use.
