If you're only going with a catback system, you're not going to see a whole lot of HP increase - X-pipe and header installs seem to the better upgrades if HP is the main concern, but *any* upgrade on your exhaust is an improvement. But to answer your question, I have an 02 GT auto and I love my Borla "Stinger" catback and Magnaflow catted X-pipe combo. Borla/Stinger, SLP and Magnaflow/MagnaPak seem to be popular choices if you what an aggressive sound and a (slight) HP edge over other systems. Some will suggest Flowmaster and I've heard some pretty good sounding Flowmaster systems, but since HP is a concern for you...other systems might make more. But again, the difference won't really be that much.

I went with the Borla "Stinger" because I wanted a loud "sound" that wasn't like all the other mustangs with Flowmaster or Magnaflow. And Borla is known for their (quality) stainless steel construction. My low quality "stainless steel" factory system looked like pure crap after just a few months, but my Borla has quite a few miles on it and still looks like it just came out of the box. I *heard* that Magnaflow uses a lower quality stainless steel in their catback systems, but I wouldn't know about that - I just know that their catted X-pipe seems to be extremely sweet. :nice:
