only real big difference i would say is dual LTE's would be better.....
Even the LTE's are not a "big" difference you a will only gain about 2 horses over the others, but the LTE's are better in the long run if you plan on doing engine work. Oh and the LTE's look sick.
If you are only doing the exhaust, intake and contoller and don't care about the look then you would be just fine on an aftermarket single and save a bunch of money. JMO
I of course am going with the LTE's, because my wife loves the way they look and I would rather spend the extra $200-300 and have the best.
Barkers are also good for people that hill shoot or drag race, because they have great flow, but they are outside the frame.
