Yep I hear you, I like em running all the way back like floor boards like Sub xs650's pic. Prefer that over the shorty style. Been done to death.
But:
For sporty look, run it back and add a GSXR muffler. I may try that even with a fat tire. I am totally with you on wanting a sporty look.
Yea, my main question is about the first few pics I posted, if I could do that with the TC bros kit.
