(BTW they are the most symmetrical of all the breakfast pastries)
The Round Rock donuts are oval, so they're only symmetrical in north/south or east/west orientation. Hmmm, I'm just 5 minutes from that place right now. Semi like a reasonable place to go after hitting the gym...
Back on topic, weight is less of a concern on a bike that in it's lightest form is 540 lbs (30 lbs is less than 6% of the bikes weight, even more like 4% with the rider). An aftermarket 4-2 exhaust is probably similar in weight to the 2013 factory exhaust. Coupled with loosing 10 lbs of centerstand, you'll drop weight on a 2013. There is also the Tadao Two Tails exhaust that allows you to retain the center stand unlike other 4-2 systems.
I think it comes down to looks and possibly sound when changing systems. Performance gains are nice, but not something I counted on when I installed my Staintune slip on. I wanted a smaller muffler and deeper sound. I got it and it feels more responsive.
