MBRP posts their dyno charts...no other manufacturer boasts that. MBRP says 9HP (with 12 - 15 lb-ft of torque gain throughout the LOW RPM band). I doubt your going to get significantly more out of anything else (especially that kind of torque throughout the low RPM). For what its worth I am putting on MBRP in the next month or two.

Thanks for all the suggestions made in this thread. We do offer real world HP and torque gains that were obtained on our bone stock JK's on our Dyno. The cat-back works sounds and performs well throughout the RPM, and also helps even more when you upgrade the intake, tune or even forced induction. Just to clarify the three different materials:
T-409 Stainless- lifetime warranty, will never rust through, but will react with snow/salt etc and oxidize...can be cleaned, but can get surface rust.
Aluminized- 3 year warranty, grayish colored material, resists rust, and awesome price point.
Black Coated-1 year coating warranty, 3 year rust through warranty. Systems are finished in a high temp black coating that resists rust, and looks unique.

To be honest we noticed absolutely no differance in performance. 
PirateKitty likes the sound
I like that it's relocated
We both like the great deal Dave at Northridge4X4 gave us.
With all that being said.... We're not entirely sold on installing the same setup on our 2nd JK.
