I'm exploring the same for my LS3 vert with NPP, and I'm probably more concerned about getting it TOO loud than you.
One well respected tuner here has advised me to do exactly what Chase just advised: leave the OE mid-pipe (H pipe) in place. He claimed it reduces drone compared to the aftermarket 3" X pipes. Not to mention, a big cost savings, especially on the vert where bracing interference becomes an issue.
