I think, according to OP's post... he wanted an EXHAUST and his primary focus was on sound. AE ftw would be my answer to your question OP. If you are worried about emissions, I don't know but going catless might cause problems. You still have the primary cats on the DP's but I don't think you will pass with just those.

Anyway, I am pretty sure you can get AE exhaust with cats in it. It is a full DP-back system too, not like many others that are merely just a muffler with tips (yet still cost more?!?!) and I dunno maybe a foot or 2 of mid pipe.

Good luck with your decision!

I would definitely go with the tune first. However, if you are still focused on what exhaust you'd like to get whether now or later, I have a Bastuck Quad and I am extremely happy with it. No drone at all.
