Our most frequently asked questions

• Highway drone? It's the number one concern on forums. This version keeps an intermediate (resonated) muffler: the sound stays full under acceleration, but the system stays unobtrusive at steady speed, ideal for everyday driving.
• What about the neighbors in the morning? The valves are controlled as on the original: system closed and discreet on startup or in comfort mode, fully open in sport mode.
• Homologation: this system is ECE / EC homologated, a real advantage for driving with peace of mind and passing the French contrôle technique.
• 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 adaptation, and a sound tuned to remain pleasant for everyday use.
