just noticed it today, when i press on the gas to accerate, i get a loud humming noise from under the right floor board, it does it also when i rev the car in park, it kinda sounds like a muffler/exhaust problem, like air breaking out

idk what could be casuing this, just noticed it, only happens when i press the gas, stops as soon as i let go

Yes I have the same problem with mine but fir only like the fIrst five min I have the car on. I had the exhuast checked and the shop said it sounded internal. I'm not to sure what it is.
