Frequently asked questions
- Highway drone? This 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 cruising speed, ideal for everyday driving.
- And the neighbors in the morning? The valves are controlled as on the original: exhaust closed and quiet on startup or in comfort mode, fully open in sport mode.
- Homologation: this exhaust is ECE / EC homologated, a real plus for driving with peace of mind and passing the technical inspection.
- Installation: the exhaust uses the original mounting points. A workshop with the right equipment typically fits it in one to two hours.
