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 system remains unobtrusive at steady cruising speed, ideal for daily driving.
  • Homologation: this system is ECE / EC homologated, a real advantage for driving with peace of mind and passing the technical inspection (contrôle technique).
  • Installation: the system uses the original mounting points. A repair shop typically fits it in one to two hours.
