Frequently Asked Questions

• Highway drone? It's the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, while the exhaust stays calm at steady speed, ideal for daily driving.
• And the neighbors in the morning? The valves are controlled as on the original: closed and quiet at startup or in comfort mode, fully open in Sport mode.
• Homologation: this exhaust is ECE / EC homologated, a real advantage for driving with peace of mind and passing the technical inspection (contrôle technique).
• Installation: the exhaust uses the original mounting points. A repair shop can typically fit it in one to two hours.

Why choose Milltek Sport?

A reference among European tuners, Milltek Sport develops each of its exhausts directly on the vehicle. Mandrel bending, clean welds and aerospace-grade stainless steel ensure an exhaust that lasts and sounds right.
