Frequently asked questions

• Resonated or non-resonated? This version is non-resonated (no resonator), the most expressive option, with more crackle on lift-off. The trade-off is that 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.
• And the neighbors in the morning? The valves are controlled as on the original: closed and quiet at startup or in comfort mode, fully open in sport mode.
• Installation: the system uses the original mounting points. A shop with the right equipment typically fits it in one to two hours.

Why choose Milltek Sport?

A reference among European tuners, Milltek Sport tunes each of its systems directly on the vehicle. Mandrel bending, clean welds and aerospace-grade stainless steel make a system that lasts and sounds right.
