question will the tail piece for the 05s and 06s work for the 07s? I may be a dumb question because I know that the bike is totally redesigned, but I know that there are a few interchangable parts between the two. I was wondering if this was one of them.
Given enough time, access to a welder, and a pipe-fitter any tail piece can be made to fit on any bike. All it takes is a little forethought, and some perseverance to get the job done.
Case in point - My friend and I did this:
All it required was cutting, then grinding off the old subframe and having a welder attach new brackets to the existing frame to fit the R6 tail. I suspect things would be a little tougher with the undertail exhaust, but a good exhaust guy (or possibly a pipe fitter) could make up an adaptor peice for you to fit the exhaust.
Basically it all depends on how far you're willing to take it.
