Hi all. Has anyone tried to fit an under body exhaust on a 999 or 749 or similar? Something similar to what the new 1199 has. I've seen a couple of 999 on Google with this done and they look really reply nice! Wanted to ask: 1 does the exhaust on a biposto work as part of the frame? If taken off would a pillion still be ok sitting on the bike? 2 any suggestions as to what other models of sports bikes have such under body exhausts so I could look at how they are layer out and possibly look for an exhaust I could use to fit on mine? Just toying with the idea but any suggestions welcome
