proper exhaust for a 5.3

[71chevystep4x4]

I'm just curious to what all you other 5.3 swappers are running size wise for exhaust? My headers are Hooker block huggers that were a LS1 application with 2" reducers, and I originally figured I'd run 2 1/2 dual pipes with a H pipe, but would like a final opinion on if just 2" would be adequate.
