Ok I just inspected it a little further, I put on the stethiscope and started the bike and ran it all around the rear exhaust and its not leaking there. I moved directly up above the flange and just below the rocker cover and ther is a opening/valley in between the two that I can stick my fingers in and the hose and can hear the leak comming from there. I cant see back there to give a better disciption of it. What would be in that area that could leak exhaust fumes??????? Anyone know what that would be?????
