Default How many Cats???

First off....I've barely peeked under my 02 RS, but when I did I saw a few cats. Once I started the enginge they all scurried out from under the car.....lol Sorry Kidding. How many Cats are there on my exhaust system....I just ordered a Borla Header and the Apex'i N1 for a WRX that I'll have fitted to my RS.....will the installation of these things get rid of any of the cats?? If so anyone know how many? I assume I'll be getting the cat inefficiency CEL soon as well, am I correct?? I suppose if I get the CEL I'll have the code pulled at the local Autozone or something and then once knowing it's the one get the mod that I've seen posted around. Can anyone tell me any other problems, minor or major, I may run into with this?? Will I lose some low end torque running the exhaust....piping 2.5" -->3.0" on the last foot or so, went with this size for upgradability for the turbo later on. Thanks guys...just wanna be prepared for anything that might come up since it's my daily driver, wanna get things done in 1 day.

well from what i understood talking to cobb.....the random tech cat isnt a wise purchase, because of the almost 90 degree bend, which ends up being less productive than the stock cat bend, which you can clearly see in the pic
