Most frequently asked questions

• Highway drone? It is the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, while the system stays mellow at steady cruising speed, ideal for everyday driving.
• What about the neighbors in the morning? The valves are controlled as on the original system: closed and quiet at startup or in comfort mode, fully open in sport mode.
• Homologation: this system is ECE / EC homologated, a real plus for driving with confidence and passing the French contrôle technique.
• Fitment: the system uses the original mounting points. A repair shop equipped for the job 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 fitment developed on the vehicle. The result: a clean installation with no modification required, and a sound tuned to remain pleasant for daily use.
