Frequently asked questions

• Highway drone? It's the number one concern on forums. This version keeps a rear resonator: the sound stays full under acceleration, but the system stays calm at steady cruising speed, ideal for everyday driving.
• Homologation: this system is ECE / EC homologated, a genuine advantage for driving with peace of mind and passing the contrôle technique.
• Fitting: the system uses the original mounting points. A properly equipped repair shop 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 tone tuned to stay pleasant every day.
