Here's the exhaust setup on my 2012 Silverado Z71. 5.3L LS, 6L80E. It's stock besides an eBay cold air intake. Stock manifolds, stock primary cats, stock Y pipe.
I welded in a 3' pipe in place of the third cat. It did not cause a check engine light or anything of that nature, just freed up a little horsepower!
It has a single in/dual out Flowmaster Super 10, 2.5 inch stainless tailpipes, and 4x18 inch polished tips out the back.
It's loud, but not clapped or obnoxious at all. It has the perfect tone in my opinion. it does not drone badly at all, but it's loud. Did I mention it's loud?
Other mods: Leveling kit, 18x10 Moto Metals w/ 33x12.5 Nitto's
