Our most frequently asked questions

• Highway drone? It is the number one concern on forums. This version keeps an intermediate (resonated) muffler: 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 operate as on the original: closed and discreet at startup or in comfort mode, fully open in sport mode.
• Fitting: the system uses the original mounting points. A workshop equipped for the job typically fits it in one to two hours.

Why choose Milltek Sport?
