Ok, so for those of you who have been following my header/x-combo escapade...I decided to change it up.
To recap-
K&N intake
JBA shorty headers
Bassani Xpipe with removeable hiflo cats
no mufflers, straight pipes
At first, i had it with the off road pipes in.
Off road pipes
this morning, I replaced the offroad pipes with the hiflow cats. The best way I can describe it is...less raspy, just as loud, but a more muscly sound.

Hi Flow Cats
Sounds good. I've been thinking about going with x pipe for a while now but have been worried about how loud it would be with straight pipes. How big of a difference is there between shorty headers and the stock headers?
ooooo this is bad. They both sound really good, and I really like the rawness of the off road version. I think it is irritatingly loud in person though... its hard to tell from the video. My new concern is how much different the H pipe is from the X. This is an X pipe, and I REALLY like it. But I have heard H pipes i REALLY like. I think it depends on the video.
Dan, where in CA are you?

Thanks for the vids. I have been saving up to get the hi-flow cat legs from Bassani. I bought just the off-road x-pipe without the cats because I was sure I'd want the offr-road setup. But, after having it for weeks now, I don't like it one bit. Way too much rasp. I think this car definitely needs cats. And those hi-flow cats really don't make it any less loud.
I'm with you, Ian. After reading/listening for some time now, I'm pretty much set on going with LT headers, catted X-pipe and my Loudmouths. I think the cats will provide just enough restriction to sound loud and muscle-car like!
Although running around with open headers like Dan did sounds pretty sweet too. ahaha

I'll be sure to post up some video when I do it (which should be sooner rather than later).
I like the rasp, but want to cut down on the volume a bit... but I am all confused now. Too many good sounding choices. I am leaning toward the catted bassani, so I have the option of going catted or not.

you could always add in an electronic cutout pair if you really wanted that open header sound at the flick of a switch.

Actually I made several posts about that over the summer becuase my friend did it to his 5.0. But is there room to put them BEFORE the stock cats? I would love that, keep what I have now and have cutouts. Even if it meant reflashing the tune when I opened it, still it would be an easy change. Would they fit tho?

yeah the "axleback" pipe and tip was custom bent. Cost me about $250.
I too have been considering cut outs...very useful for driving arround...and then makin it quiet to go in my neighborhood. I am gonna get the car up again and take measurements/pictures this weekend.
