Frequently asked questions

• Drone on the highway? This is the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, while the system stays calm at steady cruising speed, ideal for daily driving.
• 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 exhausts in England, with mandrel-bent tubing to preserve the internal diameter and a fit developed on the vehicle. The result: a clean installation, no modification needed, and a sound tuned to remain pleasant every day.
