Does my stang have a hydraulic clutch?

It's not backfire,it just sounds like it.It's like when you turn on your car with open headers,and step on it.And when the rpm return to normal you hear those booms.Every car i ever drive in that condition did that.This time it sounded like that,but worse.(An actual backfire i guess).And yes the pedal went in by itself,but it did it do little that there was no way for the engine to overev.I hit redline because it was first gear,and i got scared when i heard the boom.In that situation i hit redline all of a sudden.But by the time i hit redline the clutchpedal had already returned to normal.It all happened really fast.
