I havn't dropped the exhaust yet in favor of dr bob's instructions but I need to pick up a vacuum gauge and lines and another T fitting for it.
If I go the exhaust route will I have drop everything from the headers back?

I spent $500 to install those cats, since the car didn't have any when I bought it.

Installed an Ott X, and it made a huge difference! I've kept the old cats around just in case they re-institute exhaust testing in south Florida, but I'm getting ready to put a pair of Random-Tech cats back on, since I'm pretty sure I've solved the problem [bad MAF connector].
Best of luck-

Also, when I get to around 100mph and it starts to hesitate, if I let off to 3/4 throttle it will slowly accelerate but still hesitate. Its an on and off sort of hesitation. If needed I can mount a camera and let you guys diagnose it.

Have you noticed your gas mileage being worse lately?
You can try unplugging the battery for a while, then plug it back in and have the computer re-learn. Could also be caused by bad/broken/leaky parts.
Running around without an exhaust is REALLY FREAKIN' LOUD. I'll bet you don't get out of your driveway without being scared of the noise. I started up the supercharged GTS in the garage once without the resonators/muffler. It wasn't bad at idle, but as soon as I rev'd it, I think everyone on my block was looking out their windows. I couldn't imagine what it'd sound like without the center-section too...
