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 can appear at certain engine speeds on long journeys. If you do a lot of motorway driving, compare it with the resonated version.
• And the neighbors in the morning? The valves are controlled as on the original: closed and discreet on cold start or in comfort mode, fully open in sport mode.
• Race version: the loudest in the range, designed for the track and for sensation seekers. It is not made for quiet long-distance driving.
• Fitting: the system uses the original mounting points. A workshop typically fits it in one to two hours.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, using mandrel-bent tubes to preserve the inner diameter and a vehicle-specific fit. The result: a clean installation with no modifications needed, and a sound tuned to remain pleasant for everyday use.
