Interesting thread. I can tell you what I've done to my 2011 796.
First, I installed Arrow Dark slip ons w/out the baffles. Sounded great, and the bike ran OK. In my opinion, it was still running "factory lean."
Second, I installed a Bazazz Z-Fi fuel control unit w/the Bazzaz fuel map for the 796. I was really disappointed with how the bike ran with the Bazzaz map. It was making HUGE adjustments to richen the bike out. Way too radical in my opinion.
Third, I installed the Bazzaz Z-AFM self mapping unit. This replaces the O2 sensors and does a mapping (after a 30 minute ride) of suggested modifications to the Z-Fi map based on a suggested Air/Fuel ratio. This made a HUGE positive difference - MAJOR. The bike was running awesome and I notices a significant change in the power bands.
EDIT: Keep in mind that w/the free Bazzaz software that you connect via USB to your bike, you can trial/error changes to the fuel map manually. I did this before I installed the Z-AFM and it was pretty successful. It's just WAY easier with the AFM.
Forth, realizing that how the bike "breathes" is a combination of the air flow coming-in as well as the air flow going-out. I installed an MWR air filter with an open (top) air box. This required another mapping ride for the Bazzaz AFM system to figure out the new air flow and modify the fuel map. Once applied, I'm just telling you - the difference is significant.
So, net/net. Put on great sounding pipes that opens up the air-out. Open up the air-in. Put on a fuel management system that has a self-mapping unit that knows how to "fool" the ECU via the O2 sensors. The difference is MASSIVE.
Oh, another "must do" mod in my opinion is a 14-tooth front sprocket.
