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 heard 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 quiet at startup or in comfort mode, and fully opens in sport mode.
• Fitting: the system uses the original mounting points. An equipped repair shop typically fits it in one to two hours.

Why choose Milltek Sport?

A benchmark among European tuners, Milltek Sport develops each of its systems directly on the vehicle. Mandrel bends, careful welds and aerospace-grade stainless steel ensure a system that lasts and sounds right.
