Hey Mohawk!
I got lucky and saw a newish set of 2004-2007 on ebay which looked slightly longer, so for $49 i gave it a shot, and as suggested they are perfect. The GSXR with the top seal would be nice but i had added an additional o ring, "great minds".
The insulation that was starting to rust on the 2008, the 2007 have an addition exterior coating which should help, cost cutting in 2008 i guess.
I laid the bike down year and half ago, and got side tracked on a tesla model 3, only so much i could do to it "thank god" suspension, brakes and wheels. Just got the bike back in shape. Have a Dyno and mapping session scheduled tomorrow, so should be all systems go.
Thanks for the replies
