Most frequently asked questions

• Highway drone? It's the number one concern on forums. This version keeps a resonator (resonated): the sound stays full under acceleration, but the system stays calm at steady cruising speed, ideal for everyday driving.
• What about the neighbors in the morning? The valves are controlled as on the factory system: closed and discreet on startup or in comfort mode, fully open in sport mode.
• Homologation: this exhaust is ECE / EC homologated, a real plus for driving with peace of mind and passing the contrôle technique.
• Fitting: the system uses the factory mounting points. An equipped repair shop usually 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 inside diameter and a fit developed on the vehicle. The result: a clean installation with no adjustments needed, and a tone tuned to stay pleasant for everyday use.
