i have a 2003 stratus r/t and everytime i hit 60mph the car makes a loud annoying humming like waa waa waa waa noise and it sounds like its coming from the back beacuse people tell me its louder when sitting in the back seat. but when i go over 70 mph it quiets down.

i have drilled and slotted rotors all the way around so idk if it could be an echo? or if its the tires because one is a k106 and the other is a raptor... they are the same size but maybe it makes the car ride uneven? or maybe a bearing? any suggestions?
