I will be running 2.5" with my turbo setup i'm going to be buying. Which part number cat will be long enough to make my o2 sensor not throw a code...any? or would my best bet be to get an o2 sim and try to find someone to pass my emissions?
The only difference between a "high flow" cat and your cat is the diamater of the pipe going in and out.
boost above 8 psi? no cat is better!

i was gonna run it at about 5 for daily use and 9 for racing/having fun lol ...if i find a place for emissions i will run no cat...but if i can't, what should i use...just like a 94000 series from justmagnaflow.com or what?
53035 is a 2.25" car-sound car with one o2 boss.

shouldn't i get a 2.5" if i'm going to be running 2.5" downpipe and exhaust?

also...resonator or no resonator? i have vibrant single tip exhaust...but the tip is like 4 inches haha...i just got it in from gravana today...so i'm not sure if it'll be raspy as hell or not
It shouldn't be raspy with the turbo.
Even at 1 psi no cat at all is best.

And for the SC, what would be better? cat or no-cat?

basically a boost-senstive electric cutout? i'd think it'd be louder... however wouldn't some exhaust flow still be directed out of the stock exhaust?

^^ its not electric at all, purley actuated by boost.
think wastegate, but for your entire exhaust system. My buddy has it on his 1.8T beetle.
but yea no cat with turbo
if youw ant, get a high flow cat, then just put a pipe thru it so it looks like a cat, but is in fact a straight pipe.
Run a cat simulator, and ur scott free
ull pass visual, and the computer hook up. Drive home laughing

yes i know its non electric. it's just a similar concept to the electric cutouts. my best friend and i are busy turboing his 4 door civic.... and i'm going to make sure he does this instead of an electric cutout.
