What I meant in terms of dyno test are take the car stock, dyno it with the exhaust, drop the exhaust, bolt on the "new one" and re-dyno (don't even take the dyno off the car) and you might see some increases, but usually they only work in conjunction with other flow-mods (headers, Downpipes, High Flow Cats, Intake, etc)

Yep, you have to look at the intake/engine/exhaust as ONE BIG TUBE....if you are going to open the back end and you haven't done anything to the front or middle, your results are not going to be very fruitful. In fact, if you open the back TOO much, you'll create negative effects.

Unless you have it professionally done, you are looking at major headaches.
A lot of sensors have fits when you change the exhaust system without changing the programming.
If it were me, I'd leave it alone. Nothing good can come of it.

Not a great idea. You need the 02 sensors to talk to the computer.

At the most you should only put a cat-back system on it. In my own opinion though it's a waste of money, especially on the V6.

Aftermarket companies knowing of the problems when removing O2 sensors have manufactured "dummy" sensors which replicate a cars performance under ideal situations which tricks the computer to believing that everything is working fine. Course if you have an emissions problem you would never know as the O2 sensors would report that everything is as it should be.
I live in a non-emission testing state which would make it more reasonable to use the dummy O2 sensors and remove the cats completely which makes for better exhaust then adding a catback as we know that the cats are way more restrictive than any muffler.
