It doesn't really matter since whatever is done is done. Stay off of it until you get the O2s installed. You should tune as well.
The noise you are describing, is it a sound kind of like the opposite of going WOT (eg, kind of sounds like the car is breathing backwards - I realize this sounds kind of wonky). The coast down loudness from high rpms is normal with long tubes.
