    okay,
    i was arguing about backfires my car does this and i don't think its exactly a backfire...my 5.0 does exactly the same as the car in the vid but my PYPES make sound really tinny so its a little louder of a crackle/pop..
    not my car or friend and I'm not cracking on the video i just need some opinions on this sound in between the revs its(im not talking about camera distortion either)

    Its not a backfire. By revving the engine and immediately letting off the gas you are changing the pressure inside the muffler. Long physics explanation aside, that is the "pop" you hear.

    To be Uber Technical a Backfire is out of the Intake and a Afterfire is out of the Exhaust
