Most frequently asked questions
- Highway drone? It's the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, while the exhaust stays unobtrusive at steady speed, ideal for everyday 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 exhaust is ECE / EC homologated, a real advantage for driving with peace of mind and passing the contrôle technique (French roadworthiness inspection).
- Fitting: the exhaust uses the original mounting points. A repair shop typically fits it in one to two hours.
Why choose Milltek Sport?
Milltek Sport designs and manufactures its exhausts in England, with mandrel-bent tubes to preserve the internal diameter and a fit developed on the vehicle. The result: a clean installation with no adaptation needed, and a sound tuned to stay pleasant for everyday use.
