Hi, since i bought the car, i noticed that when the rpm is around 1050 rpm (on all mode, and around ratio 5-6) driving at 50-60 km/h, the exhaust make a lot of noise and vibration. When sitting on the second and third row, you can hear and feel it. It feel like it had an sport muffler installed.

Later on freeway, driving at 110 km/h and giving it a little acceleration, that noise and vibration were also present. This time the rpm is around 2000-2200rpm.

Any other owner have noticed that noise?
