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 may 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 OEM system: closed and discreet at startup or in comfort mode, fully open in sport mode.
• Race version: the loudest in the range, designed for the track and for enthusiasts who want the thrill. It is not meant for quiet long-distance driving.
• Installation: the system uses the original mounting points. A properly equipped repair shop usually fits it in one to two hours.
