Default performance gains felt with aftermarket exhausts

I have a 2012 WRX Hatch with a Cobb intake box, Cobb downpipe and "open source" tuned. My question after reading hundreds of aftermarket exhaust posts is;
" What are the seat-of-your-pants palpable gain variations in say all 3" diameter catback setups?"
Besides the sound differences would I really feel performance gains?
My last car was a Audi S4 that had many mods, the least felt was the Neuspeed aftermarket exhaust. Apparently, the stock exhaust tubing was so good, the $1500 cost of the aftermarket exhaust was just a better sound.
Is the '12 hatch exhaust system restrictive enough that an aftermarket catback would be "felt", like say going 30mph-60mph, 2nd to 3rd shift.?
Please post your personal favorites..thanks
