anyhow, I have the same setup, 18" res w/ OEM cats and I actually want something a tad louder at times lol. I think this thing is perfect really. Sure it's a tad louder than one might expect at lower RPMs, but it's nice and deep and sounds good, but I don't think it drones at all, nor does it affect my music or conversation with my wife. She loves it too!
And once you hit 3k (cruising on interstate at 80 mph) I don't hear a thing. It's actually pretty quiet unless I downshift and really get on it. Just cruising along with this exhaust is perfect, especially at interstate speeds. I'm VERY happy because I drive a minimum of 60 miles a day between work and school, so having a relatively calm/quiet exhaust when I need it to be (interstate) and still having an available beautiful agressive note when I want to drive sporty, romp on it and have fun... this exhaust gives me both I feel. I'm very satisfied!
If anything at all, I'd possibly consider going to the 12" resonators (if anyone ever wanted to switch for my 18's). I felt the HFC's were just a tad too loud for me, so I assume the 12" CBE would be somewhere in between the 18" w/ OEM cats vs. HFCs.

It's good that you posted this because it highlights the difference in sensitivity to the exhaust. I don't want people to shy away from the exhaust because of what I'm posting. For us, that low frequency is bothersome... but for others it's not.
As far as the resonators go, I think Tony said the only difference is for volume.
Out here in VA, cruising at 80+ is not an option unless you don't care about getting ticketed. So I'm stuck in that bad range.
