Frequently asked questions

• Resonated or non-resonated? This version is non-resonated (no middle muffler): it is the most expressive, with more crackle on lift-off. On the other hand, a slight drone may appear at certain engine speeds on long trips. If you do a lot of motorway driving, compare it with the resonated version.
• What about the neighbors in the morning? The valves are controlled as on the original: the system stays closed and discreet on cold start or in comfort mode, and fully opens in sport mode.
• Race version: the loudest in the range, designed for the track and enthusiasts. It is not meant for quiet long-distance driving.
• Fitting: the system uses the original mounting points. A workshop equipped for the job typically fits it in one to two hours.

Why choose Milltek Sport?

Customer feedback most often mentions the fit quality and a deep sound that is present but never harsh. That is the Milltek Sport signature, from the British manufacturer specialized in stainless steel exhausts.
