It's a simply 60 dollar fix that will hopefully clear it all out. I've invested only $375 overall in getting the secondary cats taken out and replaced with straight pipes, and the mufflers bought/installed.

your original post doesn't say that, did you replace the 2nd set of cats w/ staight pipes in the vid or is that mufflers only?
edit: nm see it now
