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 remains calm at steady cruising speed, ideal for daily driving.
- And the neighbors in the morning? The valves are controlled as on the original: closed and quiet on 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 technical inspection (contrôle technique).
- Fitment: the system uses the original mounting points. A repair shop with the proper equipment typically fits it in one to two hours.
Why choose Milltek Sport?
What owners mention most often in their feedback: fit quality and a deep sound, present but never harsh. This is the signature of Milltek Sport, a British manufacturer specializing in stainless steel exhausts.
