Wait and buy my LT's when i change mine out!! 
I even have and o/r x-pipe and a catted x-pipe if needed.
This probably wont happen for a couple months though lol
All in all though, i would def go LT's. Shorties to me are just a waste of time and money. They produce a little but for the money and time it takes to do them i would just go LT. Not to mention they sound so much better.

ALSO, you have to extend your 02 wiring harness with longtubes because the collectors are located further downstream than the stock manifolds, so if you do not tune it, you will get a CEL with an error code that says something along the lines of "slow 02 response," which can cause your car to run pig rich iirc. A tune can compensate for this.
Another thing to keep in mind is if you go with longtubes, you most likely will not be able to lower your car. That is my biggest regret with mine.

As it was stated above, for best gains you'll need a retune.
