Most frequently asked questions

• Resonated or non-resonated? This version is non-resonated (no resonator): it is the most expressive, with more crackle on lift-off. On the downside, 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 factory system: closed and discreet on startup or in comfort mode, fully open in sport mode.
• Fitting: the system uses the original mounting points. A workshop with the right equipment typically fits it in one to two hours.

Why choose Milltek Sport?

What owners mention most often in their feedback: fit quality and a deep sound, present but never harsh. That is the Milltek Sport signature, from the British manufacturer specializing in stainless steel exhausts.
