Get the maxspeed motor sport headers with cats, for 799$. and get the cat delete pipes for the secondary cats. No CEl and definate increase in power. Maybe about 15-20 hp. but the sound is awsome and fun to drive.
I will have dyno results soon. I did this mod to my 02 s and it really woke it up.

If you're installing the FabSpeed exhaust (either the "new" or the "old" system), they utilize proprietary midpipes, so unless you go with FabSpeed's own catted headers, you will be catless. If you want to utilize the "eBay special" headers (which are non-catted), and you want to keep the factory secondary (now the only) cats, you will not be able to use the FabSpeed system.
For what it's worth, I'm running TurboWerx headers (non-catted) with FabSpeed's "new" exhaust (yes, I"m cat-less) with my DME flashed to RoW software, and it is fantastic. There are definite power gains to be had by getting rid of the horrible factory headers, and the much lower back pressure helps throttle response quite a bit. Sound is intoxicating as well  No CEL if you run the German software.
Hope that helps.

Respectfully BMWM750 is incorrect.
I have Maxspeed headers with cats connected to fabspeed bypass pipes connected to a Che muffler. All hook up nice and without trouble.

James-
Unfortunately, I am not incorrect. If he wants to use the FabSpeed exhaust, it utilizes proprietary midpipes, so he would not be able to use the factory catted midpipes with the FabSpeed exhaust. Now, if he wants to use one of the other exhausts (such as you have done) with just the FabSpeed bypass pipes, that's a different story, and that can certainly be done.
So, to recap, if you want a catted system and you plan to utilize the FabSpeed exhaust, you will need either their catted headers, or the NHP headers that JHandy has purchased (which I still think look horribly designed).

2 cents
I would definately go with a full exhaust, but just remember that if you mix and match you may not get the best results. Each company makes their products to compliment each other. I just bought the full NHP set up although I do agree that the headers are not very pleasing to the eye. However, they did claim 5 more horse than Fabspeed, so that is why I chose them.
