best exhaust setup performance wise?

the wifey got me a gift card to the exhaust shop for christmas. i guess i been a good boy this year..

i have a spankin 2011 v6 4x4. i want performance over sound.

from what i've read i'm leaning towards the dynomax super turbo.


question 1: performance wise- single, or dual outs?

question 2: from the cat back, what diameter piping should i go for? is 2.5" good?

question 3: if i go with a single out, can i use the stock pipes or should i replace the whole thing? are the stock pipes mandrel bent?

question 4: i want my tip(s) to be black. has anybody successfully painted their tips with ceramic or hi-temp paint and would like to share some pics or advice?
