Our most 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, but the system stays composed at steady speed, ideal for everyday driving.
• Race version: the loudest in the range, designed for the track and sensation enthusiasts. It is not intended for long, discreet trips.
• 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 internal diameter and a fit developed on the vehicle. The result: a clean fitting without modification, and a sound tuned to remain pleasant every day.
