Exhaust input.

I'm not sure I fully understand what the ticking is about. How are all of these exhaust parts joined? Slip joints and clamps? Welded? V-bands? 3 bolt flanges? Ticking could come from a leaky slip joint. A fix would be either welding that spot or v-banding it. What about exhaust gasket at the manifold flanges?
I also hear that the brass rocker trunions quiet the valve noise slightly. LS engines are going to be noisy regardless, though.

My exhaust is kindkin a mess. It's 3" from the manifolds through the y pipe to a 3.5" through the Borla catback which goes to only 2.25 duals. Don't ask me why Borla did that on their catback, bit I had that before the blower so I didn't change it.

All the joints are either slip with accuclamp or butt with those 5" long 360 degree clamps clamps

Sure, it's .25 smaller but it doesn't drone. None.

My set up is similar to madmann26, only difference is I run a 3" Magnaflow cat back. No drone.
You could look into adding j tubes:

Or just change the whole system up.

I've been trying to give the sound time for me to like it with no success. I miss the clean tone of the factory exhaust with just a catback so I'm contemplating going back to that. Aside from choking out some HP, would this be asking for melted cats while still running 100% meth and 8-9 psi?

Get the idea of supplemental methanol melting your catalytic converters out of your head. Maybe if you were burning methanol instead of gasoline in the tank, and running way too rich, maybe that will cause problems with the catalytic converters. I meant to say "maybe" twice in the last sentence.

Haha noted. How foolish would it be to run the factory y pipe, I miss the sound of just the cat back? With my power level would it be "smarter" to get some high flow cats put into my off road y pipe?
