I would like to put a set of hedders on my 2011 GS to wake up the LS2 in her but I have some concerns. If I use long tube hedders what else will i need to replace (cats, mid-pipe)? What are my other options? Is there some sort of short tube hedders I can use my factory cats with and if so what is the difference in performance? What brand would be best? I know I know a lot of questions. Thanks for your help.

I would start with putting the LS3 back in it.

with Jim. You'll get plenty of advice here but more specific in the tech forum. I put an Edelbrock eforce on my 08 vert and couldn't be happier.

Good hunting

Might want to look at headers instead of hedders.

I'd go with LG long tubes. LG being both a forum vendor and located in Plano, TX, would be the way to go. I've had them on both my LS2 and LS3 C6's. I'd also suggest the high flow cats. That way if you get some troll wanting to do a visual during the annual inspection, they are on the car. Anthony also does dynamite tunes. Be a good excuse to drive the new toll road at 85 + mph and make the trip up here for the install and tune. Plenty of great motels to stay in over night near LG's shop.
