not much... the stock mid-pipe (b-pipe) is pretty good
that's why many of the exhausts only come as "axle-back" systems
if you want to go w/ full cat-back, try tanabe, greddy or apexi, but you'll notice that for the most part, the mid-pipe still has some kind of resonator
if you want to maximize your hp, go to a muffler shop and have them make a straight pipe
also, you don't mention whether or not you're changing out headers or y-pipe..?!? just don't expect too much hp increase from just the rear exhaust; mostly you'll get some sound and a few top-end hp

Hey, I'm new to the forum, but just fyi I bought an HKS cf-ti axle back, and I also got hooked up with a b-pipe that replaces the 3rd cat with a resonator...as far as power gains, you probably won't notice much in lower speeds, but if you have a functional intake, its a decent gain in the highway speed topends, and sounds great.

You can purchase the HKS CF-Ti exhaust system from www.lextasy.com. Comes with the b-pipe, not just the rear section. Mine just arrived yesterday, having it installed tomorrow 10:00AM. Will let you guys know how it is.

Same as the HKS... 
I hope you didn't get a knock off brand... There is no such thing as "same as~", there is only "it is~".
Rear section only is quiet. When you get a B-pipe + Y-pipe, that is when it starts to get loud.
