So I haven't had the time to do anything with the hose yet. The noise did change and I can hear it during the entire rev now. I am basically sure my engine itself is fine at this point and that it is something with either the cats or the heatshields. Based on this new noise clip, its probably the cats. This was taken inside the right wheel well.

I went ahead and ordered a Borescope Camera from amazon and will use it on Saturday to go into the O2 Sensor Bank 1 and check on the cats.

I still wanna do the hose method check, but I haven't had anyone around while I am off work to actually help with that. But if my borescope findings are definitive then I may skip it even though I like the idea.

Because the noise seems worse, I will probably stop driving it today and wait till I check the cats this weekend to start driving it again.
