catback=exhaust from behind the convertor. the up/down combo i specified is catless, much like 95% of the ones on the market.
i can tell you from personal experience with about 9 different WRX's that a catback will net you no improvement in the way it drives, only in sound.
you can do a HKS dp with a cutout before a cat if you install it if you are really wanting to be full legal, instead of swapping the DP out when it comes time for inspection.

when i got a 13.4 i was on 17" wheels, had a 2.0 60ft(yes..i suck at life...but it was one of the first times i've been to the track), a full interior and i was untuned. When i say untund, i don't just mean there's more power in the car..i mean that with the UTEC built in knock sensor it will pull timing to compensate for the detonation. So as i'm going down the track the car would start to pull(the CEL light would flash as a sign of detonation) and the car would back off...than it would start to pull..and back off again.
So if i can cut a 1.8 60' which i had done before, thats good for a 13.0-13.1(if 1 down low is good for 2 up top), if i can get the car tuned...i might be able to squeeze out more power but atleast it won't be pulling back the timing and studdering going down the track. I hope thats good for a .1 second descrease, and if that STILL doesn't do it, i'll put 16"s on the car and remove somethings from the interior. (the passenger seat, the spare tire, the back seats) but i don't think that will be necessary.
sure it's a 12.9...but it's still a 12 on intake, exhaust and UTEC.

900 bucks, you are pushing about 50-65 more hp then stock, and it has good driveability.
what year did you get? 02-03 is doable with the UTEC if you know what you are doing, the 04's have a dual processor ECU that causes issues with tuning, and i am not sure if they have figured out the 05 yet or not. since Nathan left TXS, i have heard it has gone downhill.

as far as year i got an 02 so i guess the utec won't be a prob. but if your calculations are correct i wouldn't be mad at a 50-65 hp gain for less than a grand... also i was on my way to oceana yesterday when a silver looked like 02 wrx came pass and basically we drove all the way down oceana they went to the commissary...just wondering if it was anyone on here
