Both have resonators but the L99 has a huge one. The LS3 has 2 smaller ones.
The Magnaflow Tru-X will be louder but not by a whole bunch. Probably enough to make it a little louder though.
The resonated x-pipe acts somewhat like a muffler and tones it down some.
I went with the resonated x-pipe mostly because that is what Magnaflow used with their 2.5" Comp cat-back. What I used was the exact parts they used. Also, by having the resonated x you'll still have kind of a muffler. With the Tru-X you won't. Not that it matters a ton.
I would say if you want it on the slightly louder side go Tru-X, otherwise go witht he resonated one.
Also, when you have the muffler shop put on the X-pipe (either one) make sure they put it as far forward as they can. In my research that's where I was told that it was supposed to be to help the most in scavenging the exhaust.

Ok thanks that put it all in perspective. I think I'm going to go with the resonated one because your car sounds awesome in the video you put.
