Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

2000 GTP gain





The other posters hit the nail on the head - you'll gain a few HP, not enough to be really noticed by your butt meter.

But exhaust work is a prerequisite for a pulley drop to the 3.5 range, which will net you 25-30 HP. And that is noticeable.
 
^ that. Exhaust works (headers) just gets you to the point where you can pulley drop safely which you'll notice the power increase more then a full exhaust would.
