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. The trade-off is that a slight drone can appear at certain engine speeds on long trips. If you do a lot of motorway driving, compare it with the resonated version.
• What about the neighbors in the morning? The valves are controlled as on the original: closed and quiet on startup or in comfort mode, fully open in sport mode.
• Race version: the loudest in the range, designed for the track and for drivers who want the sensation. It is not made for quiet long-distance driving.
• Fitting: the system uses the original mounting points. A workshop with the right equipment typically fits it in one to two hours.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, with mandrel-bent pipes to preserve the internal diameter and a fit developed on the vehicle. The result: a clean fitting with no adaptation needed, and a sound tuned to stay pleasant for daily driving.
