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 system stays calm at steady cruising speed, ideal for daily driving.
• What about the neighbors in the morning? The valves are controlled as on the factory system: closed and quiet at startup or in comfort mode, fully open in sport mode.
• Installation: fitting requires cutting the factory exhaust. We recommend having it installed by a professional.

Why choose Milltek Sport?

A reference 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.
