you've got quite a few options when it comes to slip-ons. being carbon fiber narrows it down a bit. imo the two best options for slip-ons, that offer c/f, are akrapovic or two brothers. they not only sound great and are quality made, but look great as well.
but at close to $800 for the set, you have another option, which will keep the smooth lines of the stock look and offer you great sound, not to mention save you money. swap out the stock baffles in your stock cans and place some racing baffles in them. you can buy the kit on ebay or thru (a and r mufflers), they cost about $90 and you can do the install yourself. you save tons of money this way.
i installed them on my 05 R1 and my buddy with an 04 and akrapovic's always tells me he can't tell the difference in the sound.
