Most frequently asked questions

• What about the neighbors in the morning? The valves operate as on the factory system: the line stays closed and quiet at startup or in comfort mode, and fully opens in sport mode.
• Installation: the system uses the factory mounting points. A well-equipped shop 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 internal diameter and a fit developed on the vehicle. The result: a clean installation with no modification required, and a sound tuned to remain pleasant for everyday driving.
