Lol I've been "that" asshole since I was 15. All my neighbors know me and like me so they just deal with it ha. I don't rip it everywhere but all my cars have always been loud. My favorite setup, and what I'll do if I get another 5.3 NBS, was stock manifolds/stock catted Y cut and modified for true duals, true duals with a Summit X-pipe, no mufflers, cowboy'd out the back with 5" tips. Only thing I'd change is hide the tips up under the truck somehow. Sounded awesome, loud and would pop on decel but didn't have that shitty no-cat straight pipe crackle all the time. But a 6.0 definitely needs a muffler, I personally think that Aero is gonna be perfect, either that or like an 18" magnaflow round body
