Just as an update, I did downpipes and resonator delete after this mod and they made a huge difference (especially the resonator delete!). I still have my secondary cats intact. I like the sound now. Pretty aggressive, with just a little drone. I'm probably going to end up redoing this (or upgrading to the real thing) at some point because I hear the bands inside vibrating once in a while. They must have worked themselves loose over time.

For anyone doing this mod, I recommend to have the holes welded shut instead to avoid the clamps from loosening and rattling down the line.
