alright so yesterday i was driving along and all of a sudden i heard my right exhaust pipe start rattles.. I just thought maybe it was hitting something and i would adjust it when i got home. I keep driving along and all of a sudden my whole car starts to shake. When i would get on a gas and left off it would shake ALOT and make the whole car feel fucked up. When it was shaking I could literally see the dash, doors, and the change in my ashtray was even moving. What could be wrong with my car? I was thinking maybe a motor mount? My buddy said it could be the water pump and another said it could be the whole exhaust is loose and is making the whole car shake? Can anyone help me!!
