You should be in the ballpark of a 25 WHP gain and around 40 with a CAI...Could be less... but I'll throw that out for a ball park...

Can't help you too much with the x pipe, that will mostly improve your flow and sound. Because of no back pressure, you might loose a slight amount of low end torque.

I just put on a complete system from Kook's 1 7/8 headers X-pipe and full cat back with a roto-fab CAI. I have not done the dyno tune yet but plan to this week. The car feels a lot faster from start to top end. I don't know what the gains are but I'm verry happy with it. The car sounds nice at idle and cruising speed and great when you get into the high RPM's. I did not try it with out the X-pipe so I'm not sure how much of a difference it makes or doesn't make I just know i'm happy with how it came out.
