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 unobtrusive 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 on startup or in comfort mode, fully open in sport mode.
• Installation: the system uses the factory mounting points. An equipped workshop typically fits it in one to two hours.

Why choose Milltek Sport?

Feedback from owners most often points to fit quality and a deep tone that is present but never harsh. That is the signature of Milltek Sport, a UK manufacturer specialized in stainless steel exhausts.
