Look at the F.I thread for their dynos stock vs FI. First post in thread.

Fast Intentions exhaust is here! (continued)

If the exhaust isn't chambered and the piping is the same, the power difference will be within a few hp. Only the bends will slow things down. Regardless, of the two mentioned, Fast Intentions makes the superior product. I would also recommend looking at Motordyne's offering as well. It has a HFC option as well and makes comparable gains. The big difference with Motordyne is their piping gets larger as it gets further away from the engine and they claim it will not rasp with TP's or HFC's.

Also consider that the Stillen is one of the few exhausts that are heavier than the stock unit, while just about every other one I've seen is lighter by 5-20 lbs. By itself it doesn't matter too much, but every bit adds up if weight loss is also a concern.

I'd second the suggestion for the Motordyne CBE. Their sound and gains are competitive with Fast intentions, while having added modularity. I'd have gone with them had I had a larger budget.

The CBE alone should be because you're still using Stock cats. When you start getting into LTH, HFC, TP territory, that's when you start going beyond legal limits in Cali.
