Our most frequently asked questions

• Highway drone? It is the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, while the exhaust stays unobtrusive at steady speed, ideal for daily driving.
• Race version: the loudest in the range, designed for the track and for enthusiasts. It is not meant for quiet long-distance driving.
• Fitting: the system uses the original mounting points. A workshop with the right equipment typically fits it in one to two hours.
