upgrade

I've been looking for a new bike for a little white now and came across a 2011 Gen4 for 4k miles for a great price so I jumped on it. I'm in love with this bike. It's such a nice upgrade over a Gen3. Everything about it is so much nicer. Except one thing. The trunk on this thing is a joke...

I just picked up a 2011 ZX-10r ABS and have been searching the forum for a few days now and the internet reading all I can about the Gen 4. It seems there is a "must do" list of upgrades, just checking to see if I'm missing anything including the little things: 1) ECU Flash 2) Slip-on/Midpipe...
