I have a fully catless AE setup and I don't think it's really that loud either. I don't know that it would get a whole lot louder. Someone here had a similar set up (Mr. 5 maybe?) where they added HFC's to their catless AE exhaust and they said that the difference wasn't that large.

Personally, I think it gets loud under boost though

I've heard a fully catless AE in person, and it sounds quite a bit raspy. I'm not sure the slight sound increase would be worth the rasp to delete them IMO.

^Are you sure it's an AE? I have no rasp and I have catless downpipes.

Yes. AE catless exhaust with AR downpipes and resonated tips. Nothing but rasp. It was an auto.

That seems very odd as I've never experienced rasp. MT, AA catless DPs, new style tips.
