I'm picking up my 03 GT on Saturday! 
After the break in period, I want to get some more performance out of it. 2003 Automatic GT.. what would you suggest? Will I see any real gains from an O/R X pipe and 1 chamber flowmasters? For the price, whats the BEST bang for the buck (gears are out of the question cause I'd need the chip, and I don't have that kind of money yet)

Even though I love my exhaust, my best mod so far was my most recent; 4.10's. Ultimately, it's up to you. Good luck!
