for the price, i woulldnt recommend it just to have when your oem drive shaft is fine. now if youre having vibration or other problems with your oem drive shaft, then i would buy the aluminum one. i do have one and like it but it wasnt a wow factor by no means. it looks 100x better and it took away the little vibration i was getting from the oem one.

There is no "performance gain" in the conventional sense. Like a lightweight flywheel/clutch assembly it reduces rotating mass meaning that it takes less power to accelerate those masses.
So, right off the bat the any gain will only occur when accelerating, and that gain will only be maximised under maximum acceleration. This means that if you race competitively, or drive very spiritedly, it may be beneficial and/or pleasurable. If however you are the sort to always shift at 3000 rpm, and not "wring things out" you will find you would much rather have the $300 back...

Crown Vic cop cars have them. Does anyone know if they are a direct swap? I know they share the 4.6 too. I ask on account of the fact that there are a bazillion CV cop cars out there and if they are in-fact a direct swap, you could probably pick one up in a yard for a lot less.

How do you feel about your bbk shorty headers? I think JBL makes some too?
What kind of gains did you see once you put those on?
