Well,

After days/weeks of reading, I decided on the Magnaflow (16740).. I must say the install went VERY smooth. You can have it done by yourself in under an hour. I didn't even lift the truck up to install it. The only other option I was looking at was a Borla with the split rear exit behind the tires. I just couldn't justify the price.
Sound - The sound is pretty darn quiet. I wasn't looking for loud though so I'm happy with it. I simply wanted the BEST FLOWING exhaust with minimal sound. It is deeper than factory obviously, but in my opinion, it should have came from the factory sounding this way. I'll have some pics up within the next couple days if anyones interested in it.

I'm also considering LT Headers if I can find a deal which is another reason I didn't want LOUD.

I have a 6.0 2007.5 truck & was worried about drone. If you want an exhaust around $450 shipped that flows with the best and don't want to wake the neighbors, this is definitely the one.

expect it to get a little louder as the packing breaks in. not a ton, just a little more noticeable

Headers will make your truck much louder,
good, but much louder

Yes indeed. You can always put a smaller muffler in front of it though.
