Most frequently asked questions

• Resonated or non-resonated? This version is non-resonated (without resonator): the most expressive option, with more crackling on lift-off. The trade-off is that a slight drone can appear at certain engine speeds on long trips. If you do a lot of highway driving, compare it with the resonated version.
• What about the neighbors in the morning? The valves are controlled as on the original system: closed and quiet on startup or in comfort mode, fully open in sport mode.
• Fitting: the system uses the original mounting points. A properly equipped repair shop usually fits it in one to two hours.

Why choose Milltek Sport?

Owner feedback most often points to fit quality and a deep, present tone that is never harsh. That is the hallmark of Milltek Sport, the British specialist in stainless steel exhausts.
