the exhausts are different?
Yes, well the 1100 has the full system. The slip-on might be the same pipe (don't know diameter yet), but the kit will have a different part number because of the ECU.
it doesnt say, but is that 80's tank pearl white or just white.
A lot of unknowns at the moment for you and I both, but I'll guess that it will be the same white on the 1100S. I don't know if it is the same paint as the 696 though... should have more specific info soon enough though!
