what headers do you have on there now? Or are they just the stock manifolds?
Anyone who knows anything about GM LS engines knows you'll see the most power gains from longtubes.
Since you have an LTZ, I'd assume that money isn't a big issue, so I'd recommend Dynatech, Stainless Works, American Racing, Kooks, etc. Go with one that has a matching high flow catted Y-pipe.
