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?
What customers mention most often: fit quality and a deep sound that is present but never harsh. This is the Milltek Sport signature, from the British manufacturer specialized in stainless steel exhausts.
