Frequently asked questions

• What about the neighbors in the morning? The valves are controlled as on the factory system: closed and quiet at startup or in comfort mode, fully open in sport mode.
• Installation: the system uses the factory mounting points. A repair shop with the right equipment usually 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 itself. The result: a clean installation with no modifications required, and a sound tuned to stay pleasant for everyday driving.
