FMF exhaust for a 1000rr 2006

I'm looking at getting the FMF exhaust for my 1000rr. i heard it on a 600cbr and it sounds nice. not to loud or to low and deep sound.anyways what do you guys think? what's the performance on it? side questions fireblade is that only the red and black cbr's or what?

    never really hear a lot of reports on the FMF so cant comment too much on that one but Fireblade is the European designation for the 1000RR.

in america it is 1000rr, every where else in the world it is a fireblade

dont know why just is
