We're finally ready o remove the exhaust itself.
Loosen the bolt that connects the exhaust to the Y-piece.
2 more allen bolts between the exhaust and the tail sub frame, then wriggle the exhaust off.
Then remove the plastic cover on the left hand side (2 allen bolts), underneath the airbox. Also remove the heat shield covering the Y-piece. You'll fist have to take out the bolts of the lower front fairing plastic that attach it to the heat shield. No need to take it off entirely, it bends away far enough to get the heat shield off. The shield itself is still fixed with 2 more allen bolts. Get these out and you have free access to the Y-piece.
