Duy, on the 28th you can see and hear both my and Benny's systems (as well as a dozen others) and also understand the comparative costs and gains. I have no stake in what you do but my usual approach to this sort of problem is to choose patience and direct comparison for a good decision.
Kris, there were three components to your choice: performance, noise and wallet. Damien is quite right that the standard manifold is a piece of crap but then in performance terms so are the rear mufflers. Every step of performance will increase the noise. I think there is enough information in the above to help you choose but if you make the flying leap to the complete system then I assume that you will have costed in taking a step back again (more muffling) if it is too loud. If headers appeal, one approach might be to do them and the cats and then consider the rear mufflers after you know where you are up to on the dyno and the noise perception.
