well in that case i would stick with the fmf powerline exhaust.It's way quiter than the hmf and it uses no packing.Not to mention it's all stainless steel so it's quite durable.
It is slightly louder than stock,not much volume wise but more of a deeper exhaust tone.It's not obnoxious or annoying in anyway.
The other option is a supertrapp IDS2 or IDSX....i think it's the ids2 they make for the rinny.You can tune that muffler to either louder or quiter with the number of discs installed under the enclosed end cap.I have heard some ups and downs of this muffler but from personal experiences from friends they have had very good results and experiences from the supertrapp mufflers.
