Frequently Asked Questions

• What about the neighbors in the morning? The valves are controlled as on the original: closed and discreet on startup or in comfort mode, fully open in sport mode.
• Fitting: 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, using mandrel-bent tubing to preserve the internal diameter and a fit developed on the vehicle. The result: a clean installation without modification, and a sound tuned to remain pleasant for everyday driving.
