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. The trade-off is that a slight drone may appear at certain engine speeds on long journeys. If you do a lot of highway driving, compare with the resonated version.
• What about the neighbors in the morning? The valves are controlled as on the original: closed and discreet at startup or in comfort mode, fully open in sport mode.
• Fitting: the exhaust uses the original mounting points. A well-equipped repair shop typically fits it in one to two hours.

Why choose Milltek Sport?

Feedback from users most often mentions the fit quality and a deep tone that is present but never harsh. That is the Milltek Sport signature, from the British manufacturer specializing in stainless steel exhausts.
