Frequently asked questions

• Resonated or non-resonated? This version is non-resonated (no resonator): it is the most expressive, with more crackling on lift-off. The trade-off is that 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.
• What about 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 sound enthusiasts. It is not intended for discreet long journeys.
• Installation: the system uses the original mounting points. A workshop with the right equipment usually fits it in one to two hours.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, with mandrel-bent tubes to preserve the internal diameter and a fit developed on the vehicle. The result: a clean installation with no adaptation required, and a sound tuned to stay pleasant for everyday use.
