Most frequently asked questions

• Resonated or non-resonated? This version is non-resonated (no resonator): it is the most expressive, with more crackling 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 highway driving, compare it with the resonated version.
• And the neighbors in the morning? The valves are controlled as on the original system: closed and discreet at startup or in comfort mode, fully open in sport mode.
• Fitting: the system uses the original mounting points. A repair shop with the right equipment usually fits it in one to two hours.

Why choose Milltek Sport?

Owner feedback most often highlights the fit quality and a deep sound that is present but never shrill. It is the signature of Milltek Sport, a British manufacturer specializing in stainless steel exhausts.
