The questions we get asked most often

• Highway drone? It's the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, but the exhaust stays calm at steady cruising speed, ideal for everyday driving.
• What about the neighbors in the morning? The valves are controlled as on the original system: closed and quiet at startup or in comfort mode, fully open in sport mode.
• Homologation: this system is ECE / EC homologated, a real advantage for driving with peace of mind and passing the technical inspection (contrôle technique).
• 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?

A benchmark among European tuners, Milltek Sport develops each of its systems directly on the vehicle. Mandrel bending, careful welds and aerospace-grade stainless steel ensure a system that lasts and sounds right.
