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 exhaust remains unobtrusive 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.
• Fitting: the system uses the original mounting points. A workshop with the right equipment typically fits it in one to two hours.

Why choose Milltek Sport?

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