Frequently Asked Questions

• What about the neighbors in the morning? The valves operate as on the original: the exhaust stays closed and discreet at startup or in comfort mode, and fully opens in sport mode.
• Fitting: the system uses the original mounting points. A workshop with the right equipment typically fits it in one to two hours.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhaust systems in England, using mandrel-bent tubes to preserve the internal diameter and a vehicle-specific fit. Result: a clean installation with no modification needed, and a tone tuned to stay pleasant for everyday driving.
