I doubt if it is really worth the money you would be laying out for something that effectively the same.
They are marginally louder. I don't think the sound is much different in the pitch. Both are pretty deep. It's not like the difference between corsas, which are high pitched, and borla or b&b.
A good friend of mine has a very similar setup to mine, both had long tubes, CAI, x-pipe... He has bullets, I have stingers. We have ridden together in each car as well as followed each other. We both agreed that his is a just a bit louder but his also has a bit of a droan around 1800 RPM that mine does not have. Other than that, there is just not much difference.
I would stick with what you have.

I want it a bit louder and deeper w/o ditching the mufflers completely; done that and the resonance was killer.
