Frequently asked questions

• Highway drone? It is the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, but the system stays calm at steady speed, ideal for daily driving.
• Valveless: the system sounds open at all times. On a vehicle with factory valves, a valve delete module may be needed to avoid a warning light (see fitting information).
• Homologation: this system is ECE / EC homologated, a real plus for driving with peace of mind and passing the contrôle technique.
• Installation: the system uses the factory mounting points. A workshop typically fits it in one to two hours.
