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, but the exhaust stays calm at steady cruising speed, ideal for everyday driving.
  • And the neighbors in the morning? The valves are controlled as on the stock system: closed and discreet 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 contrôle technique.
  • Fitting: the system uses the original mounting points. A well-equipped repair shop typically fits it in one to two hours.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhaust systems in England, using mandrel-bent tubing to preserve the inner diameter and a fitment developed on the vehicle. The result: a clean installation without adaptation, and a sound tuned to stay pleasant for daily use.
