Most frequently asked questions

• Highway drone? It is the number one concern on forums. This version keeps an intermediate (resonated) muffler: the sound stays full under acceleration, but the system stays calm at steady speed, ideal for everyday driving.
• Homologation: this system is ECE / EC homologated, a real plus for driving with peace of mind and passing the French technical inspection.
• 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, with mandrel-bent tubes to preserve the internal diameter and a fit developed on the vehicle. The result: a clean installation without modification, and a sound tuned to stay pleasant for daily use.
