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 highway driving, compare it with the resonated version.
• What about the neighbors in the morning? The valves are controlled as on the original system: closed and quiet at 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 meant for quiet long-distance driving.
• Fitting: the system uses the original mounting points. A repair shop with the right equipment 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-bent tubing, clean welds and aerospace-grade stainless steel make for a system that lasts and sounds right.
