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 can appear 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 original: the system stays closed and discreet at startup or in comfort mode, and fully opens in sport mode.
• Fitting: the system uses the original mounting points. A workshop with the right equipment usually fits it in one to two hours.

Why choose Milltek Sport?

What comes up most often in customer feedback: fit quality and a deep sound that is present but never harsh. This is the signature of Milltek Sport, a British manufacturer specialized in stainless steel exhausts.
