I have a 2011 2LT Camaro and I was wondering what the best full exhaust setup would be for maximum horsepower gains?

You're not going to gain any crazy HP on these cars with an exhaust. You might gain something, somewhere by changing the stock exhaust to a full 2.5" system, but even that is conjecture.

Now, if you aren't privy to emissions testing, throwing long tube headers on your car (plus a tune, which you'd need at that point) will give you some serious power, and if you do have emissions testing but it isn't super strict, you might be able to get away with running high flow cats with headers. But then with any exhaust you'll want to add the Magnaflow 11386 resonated x to keep the rasp down and the drone in the car manageable.

Honestly with whatever headers / cats combination you went with, if you grabbed the Magnaflow 11386 and, say, the catback off an LS3 SS, you could just remove the resonators and H pipe and weld the 11386 up and you'd have a full 2.5" exhaust that flows better (in theory) and is louder. I'd think that's the cheapest route, and it would just sound like a slightly more muted version of a muffler delete or NPP exhaust with the valves open.
