Is it possibel to remove the flow tubes, mufflers, and tailpipes as one piece without doing too much disassembly? Maybe even jsut lettign the rear end hang down to make more clearance?
That's what I plan to do. Although that bypasses the muffler as well. 
I am looking at a pair of muffs with dumps to run in the summer (top down) then I can put the full length back on for inspections and winters...
