Frequently asked questions

• Highway drone? It's the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, but the system stays calm at steady cruising speed, ideal for everyday driving.
• And the neighbors in the morning? The valves are controlled as on the factory system: closed and quiet on startup or in comfort mode, fully open in sport mode.
• Homologation: this system is ECE / EC homologated, a real plus for driving with peace of mind and passing the French technical inspection (contrôle technique).
• Fitting: the system uses the factory mounting points. An equipped repair shop typically fits it in one to two hours.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, with mandrel-bent tubing to preserve the inner diameter and a fit developed on the vehicle. Result: a clean installation with no modification needed, and a sound tuned to stay pleasant for everyday driving.
