Frequently asked questions

• What about the neighbors in the morning? The valves are controlled just like the original: closed and quiet on startup or in comfort mode, fully open in sport mode.
• Fitting: installation requires cutting the original exhaust. We recommend having a professional fit it.

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 needed, and a sound tuned to stay pleasant for everyday driving.
