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 highway driving, compare it with the resonated version.
- And 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 sound enthusiasts. It is not meant for quiet long-distance driving.
- Fitting: the exhaust uses the original mounting points. A repair shop typically fits it in one to two hours.
Why choose Milltek Sport?
