The questions we get asked most often

• Highway drone? It's the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, but the exhaust stays calm 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 advantage for driving with peace of mind and passing the technical inspection (contrôle technique).
• Fitting: the system uses the original mounting points. A repair shop with the right equipment typically fits it in one to two hours.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, using mandrel-bent tubes to preserve the internal diameter and a fit developed on the vehicle itself. The result: a clean installation without modification, and a sound tuned to remain pleasant for everyday driving.
