Takeuon, thats for the kind words. The Hugger(forgot about that mod) I carried over from my 01 Busa which I traded in for the 08. It was a while back and can't recall where I purchased it. It could have been an eBay purchase. I was never really happy with the fit on either bike, as you can tell by the cable tie I am using to secure it to the swingarm brace. I does the job and does match the rest of the bike however.
The rear passenger pegs I believe you inquired apon, were not from Gillies (just my front rearsets). They were just eBay purchases of Black pegs and were about $30.00 US. If you want the actual seller let me know and will look him for you, but he advertises on eBay almost all the time. You can get them in any color you like. They are of good quality and have no complaints with them.
Also I did not remove my exhaust mount hanger on either side, they are used to hold the Givi adaptors. I purchased those from Twisted Throttle who I have dealt with a few times in the past and have nothing but good to say about them.
As for the rear tail (shovel), I had it off originally, but the Givi luggage adaptors mount to it to secure the back end of the setup. I have seen (I believe it was warchild) with his setup without the tail and the bracket going from one side to the other unsecured, but felt that this may not be as stable as with the tail, so functionality won out on that occasion.
Obviously one of the other mods I forgot to mention was the removal of the decals. It is nothing against the busa kanji emblem which I truly admire and respect. It is in my humble opinion,a very tasteful symbol to represent the world's fastest production motorcycle. I just wish that suzuki would have placed it on the bike not with stickers, but with a true automotive emblem, fashioned after the great marquees. Something metalic, not to big, with gold or perhaps titanium plating to set the bike apart! I mean, "Stickers" for gods sake, this is not a childs' toy we are talking about. I personally feel it deserves more than that. Best analogy I could give would be the racing strips on many of the earlier NA muscle cars. You don't see racing strips on the top end German, Italian or even Japanese vehicles. That all being said, I financially cannot afford the types of high end exotic cars of which I speak, so I decided to go one better and purchased one of the worlds fastest, smoothest and best looking machines on the planet!
Take care all.
