I would say 15-20whp with a test pipe. depends. it's not too loud unless you get on it. then again, that's just my opinion of loudness.

According to your cars profile, your on a flashed stock ECU. I don't know what's been reprogrammed, but stock ECU's like to see a cat or some kind of reading from the second O2 sensor. From my understanding it's turbos that don't like cats.
Is it worth it...?
Depends on if your willing to deal with any legalities, and yes it will be louder.
We try not to guess horsepower gain here, because there are too many variables in tuning a car. If you really want to see what it does; do it, and lets us know what you get.

thank you for the respondes. The turbotrix going to reflash my ecu after they installed the test pipe. Yes my question is what kind of legal problem can i have if the police find out i don't have cat?i am not sure it is worth the risk to do it. i am sorry my english if you dont understand what i would like to ask. I am in the usa only couple of years.
thanks :

you can get a no-cat ticket which is immediate impounding of ur car and like a 900 dollar ticket from what im told by my local pd. the chance of them lookin unless ur from california or something is very unlikly though, and u wont even get close to passin emissions.
