Frequently Asked Questions

• Highway drone? It's the number one concern on forums. This version keeps a resonator (resonated): the sound stays full under acceleration, but the system remains calm at steady speed, ideal for everyday driving.
• Valveless: the exhaust is loud at all times. On a vehicle fitted with factory valves, a valve delete module may be needed to avoid a warning light (see installation notes).
• 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. An equipped repair shop typically fits it in one to two hours.
