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 system stays unobtrusive at steady cruising speed, ideal for everyday driving.
• Fitting: the system uses the original mounting points. A repair shop with the right equipment typically fits it in one to two hours.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, using mandrel-bent tubing to preserve the inner diameter and a fit developed on the vehicle. The result: a clean installation without modification, and a tone tuned to stay pleasant for daily use.
