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 car stays settled at steady cruising speed, ideal for everyday driving.
  • And the neighbors in the morning? The valves are controlled as on the original: closed and quiet at startup or in comfort mode, fully open in sport mode.
  • Homologation: this system is ECE / EC homologated, a real plus for driving with peace of mind and passing the roadworthiness inspection.
  • Installation: the system uses the original mounting points. A shop with the right equipment typically fits it in one to two hours.

Why choose Milltek Sport?

A reference among European tuners, Milltek Sport tunes each of its systems directly on the vehicle. Mandrel bending, clean welds and aerospace-grade stainless steel make a system that lasts and sounds right.
