best mods so far...

Carbyte also disables the DFM= cylinder deactivation so the engine is in v8 most of the time. Makes it sound better when running a louder exhaust.

BacDoc,

Thank you and appreciate the Intel on the exhaust/CarByte. As you mentioned, I'm inclined to do the muffler vice the cat back system. Good to hear CarBYTE is a "plug and go" system...definitely don't want to get into "tinkering" with any engine mods.

I’d say go with muffler. Borla makes really good mufflers. I have the pro xs and sounds really good. Not too loud but you know it’s there. You can have a conversation and my kids sleep in the Yukon. And it’s way cheaper. If it’s purely sound you’re going for id def just get a muffler. They run less than $200.
