Another oooh yes from me too. Like you I went from 996 with Termi's to the stock (brand new) 999. It is far too quiet.
Nice new pipes now and the proper roar is back although I too get the "goat" noise away from the lights sometimes (my wife though it was my fault saying I must be doing something wrong!). The bike is totally different with a new exhaust system and I'm loving it.
Now get a single seat unit on and go have some fun
