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 system remains unobtrusive at steady cruising speed, ideal for daily driving.
• Race version: the loudest in the range, designed for the track and driving enthusiasts. It is not made for quiet long-distance trips.
• Fitment: the system uses the original mounting points. A properly equipped repair shop typically fits it in one to two hours.

Why Choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, with mandrel-bent tubes to preserve the inner diameter and a fit developed specifically for each vehicle. The result: a clean installation with no adaptation required, and a sound tuned to stay pleasant for everyday use.
