Actually, on my '09 there seems to be 10 bolts that hold the entire exhaust system in place... from tip-to-tip.
I have a Clymer 1986-2007... if you look at page #207 you'll see the trickiest of the bolt/clamps in question are around the Rear Heat Shield... #10 and #18 particularly.
There's also two little bolts further down, holding the BIG FLARE part of the Rear Heat Shield to the actual muffler (both are hard to reach)...
and these two little bolts aren't numbered in the Clymer (in fact, they only show ONE of them, but there IS two bolts).
I've been working on this all day, and it's been difficult... the main release bolt that would make this easy is #10...
but it's obscured by the Clutch cover... it's visible, you can almost reach it... but it's slightly UNDER the Clutch cover, so a socket won't fit.
Strangely, I can't remove the clutch case without removing the exhaust first... so it's kind of a Catch22.
The exhaust system mount is by-far the most confounding thing I've found so far... everything else has been easy, forseeable...
but even when I get the back tire off tomorrow, I still can't see how I'm going to get access to some of these bolts.
