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 other hand, a slight drone may be noticeable at certain engine speeds on long journeys. 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: closed and discreet on startup or in comfort mode, fully open in sport mode.
• Race version: the loudest in the range, designed for the track and sensation seekers. It is not made for quiet long journeys.
• 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?

What owners mention most in their feedback: fit quality and a deep sound that is present but never harsh. This is the hallmark of Milltek Sport, a British manufacturer specializing in stainless steel exhausts.
