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?

A reference among European tuners, Milltek Sport tunes each of its systems directly on the vehicle. Mandrel-bent tubing, clean welds and aerospace-grade stainless steel make for a system that lasts and sounds right.
