Dan, I've been leaning towards getting just the axle-back Flows with the stock pipes. I had 40-series Deltas on my 2000 GT, but I understand it's totally different now with no pipe after the muffler. What didn't you like about the sound? Was it not noticably throatier/louder than stock? Too much drone even with the stock pipes?
Have you looked at Corsa's site? They claim no drone at all from their axle-back system.

I went from stock, to Flowmaster axle back, stock mid (some drone, great roar, though), to Magnaflow axle back, stock mid (Roush conversion, better than stock, not as manly as the Flow's), to Magnaflow axle and hi-flo x-pipe (appreciably louder, very little drone). I love the current setup. Sounds evil WOT, growls like a caged beast coming down the gears. Dunno if you compared your new H v's the OE midpipe, but my x must've been 10lbs lighter!
I think the setup I have is probably something like what you're looking for - rare drone but enough thunder to set off car alarms, if you try.

Go with Bassani. I absolutly love the look and sound I am getting from them. Very nice rumble at idle and at WOT they sound amazing. I get tons of compliments on them. I have a video where you can hear them here:

I had a 04 gt and had flowmater 40 series with off road H-Pipes and the sound was great but the exhaust fumes were horrible. I just recently bought a 06 gt and went with the SLP Loudmouth exaust and it sounds just as good as my 04. Best of all the SLP Loudmouth was one of the cheaper of the variety of exaust systems without the fumes.
I'm running an 05 GT with the JBA Longtube Headers with the Catted H-Pipe and the stock mufflers. I don't get any drone and when you punch it you defineitely hear it. The added bonus is horsepower since the axlebacks give you squat.
The Diablosport Predator for the 05 won't allow you to turn off the O2's but I think the SCT XCal-II wil.
