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.
• What about the neighbors in the morning? The valves are controlled as on the factory system: closed and quiet at startup or in comfort mode, fully open in sport mode.
• Race version: the loudest in the range, built for the track and for drivers who want the sensation. It is not made for quiet long-distance driving.
• Fitting: the system uses the factory mounting points. A shop with the right equipment typically fits it in one to two hours.
