Our 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 appear 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: the system stays closed and discreet on startup or in comfort mode, and fully opens in sport mode.
• Installation: fitting requires cutting the factory exhaust. We recommend having a professional carry out the installation.

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 ensure a system that lasts and sounds right.
