I hear ya!
We would really really like to hear it. I'm been thinking of changing out my Flowmasters for the Ultra Flo welded for a while now. I already have the X.
Does it have a deeper tone? I know the X more than likely quieten it down some.... it did mine.
Over here we've been wanting a good sound clip of the Ultras.
