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. The trade-off is a slight drone that may be noticeable at certain engine speeds on long trips. If you do a lot of highway 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 quiet on startup or in comfort mode, fully open in sport mode.
• Race version: the loudest in the range, designed for the track and driving enthusiasts. It is not made for quiet long-distance driving.
• Fitting: the system uses the original mounting points. A well-equipped repair shop typically 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. That is the Milltek Sport signature, from a British manufacturer specializing in stainless steel exhausts.
