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 line stays unobtrusive at steady speed, ideal for everyday driving.
- What about the neighbors in the morning? The valves are controlled as on the original: the exhaust stays closed and discreet at startup or in comfort mode, and fully open in sport mode.
- Homologation: this system is ECE / EC approved, a real plus for driving with peace of mind and passing the French technical inspection.
- Fitting: the system uses the original mounting points. A repair shop equipped for the job typically fits it in one to two hours.
