Muffler Options for 05 Burb

[martincsm]

2005 1500 Z71 burb. Recently got a performance tune from Black Bear performance www.blackbearperformance.com and now looking to do some exhaust work. Not looking to do a full cat back. Just want to replace the muffler.
1st, what is the stock pipe diam. From what I have seen, I think it is 2in.
What type of muffler should I look at?
Was interested in the flowmaster 50 series because it isn't to loud but has good tone when you get it on it.
This is a family rig for the wife so keep that in mind.
Thanks

Just installed a Cherry Bomb Vortex on my 06 5.3 last night. Sounds great. It is more mellow than what most on here like, but it gained the approval of my wife and kids, so i'm happy with it. And it was enough to catch the attention of my neighbor next door that has a Mustang GT when i went up the road last night.
