I have the very same one! You are right, it does sound lovely. At high revs, I get a bit of a pop between 1st, 2nd & 3rd. Keep an eye on your header pipe clamp and fixing bolts, mine have started rusting pretty bad (original parts, not Scorpion, so everybody is at risk of it). A wire brush and some rust remedy seem to be holding it back.
That is a great looking pipe! The advantage to the Scorpion over others is that you don't have to replace the fiberglass packing later on. I have one on my Honda CB300R and it is not offensive in noise either.
