First all, i want to thank everyone in the V6 applications section for all the help.
I decided to break down and have a duel exhaust fabricated by a local shop. After reading endless entries and listening to a few audio clips, here is my decision.
Divorced duels after the cats, no crossover, and Thrush 2 chamber Welded Mufflers. From the sound clips I've heard, the thrush mufflers sound just slightly more aggressive and a whole lot cheaper than the flow 40's.
Now I do have a question I hope everyone can lend a hand with. Would dumping/turndown the mufflers before the rear axle or running tailpipes out the back give a better sound and should I stay with the stock 2.25in diameter or have a pipe created to open the diameter after the cats up to 2.50 or even 3in?
Once again thanks for all the help.

Ok, I think i decided to dump the exhaust before the rear axle. From what i understand this gives you a slightly deeper and louder sound. However, I am still wondering if it is feasible to open the exhaust diameter after the cats to either 2.5 or 3in into the mufflers. Will the sound differ if the pipe diameter is changed right after the cats?
I thought the crossover pipe was only needed for engines that had an odd firing order. Since the 3.8 v6 has an even firing order, I didn't think a crossover was necessary. Of course this is based on a forum I read somewhere.
If i can find where i read that, I'll post a link to it.

i saw that, but i also saw all of these reasons why you should. all of which are true...
Then why do some people still recommend including an H-pipe in their V6 exhaust system? Here are the arguments I've heard.
# The H-pipe produces a venturi effect. As each exhaust pulse shoots past the equalizer tube it creates a slight vacuum and a pressure drop on the other side of the tube. In an even-fire V6 engine, this occurs just as the next exhaust pulse leaves the opposite cylinder bank. As the pressure drop alternates from side to side it reduces back pressure and allows the exhaust gases to travel more freely through the system. [An interesting theory, but not one, so far as I know, advanced by any manufacturer of H- or X-pipes. ]
# No exhaust manifold flows perfectly. Even with the V6's even firing sequence, there will still be momentary pressure imbalances between the two banks of cylinders. [Probably true]
# The H-pipe produces a better exhaust sound than straight pipes. [?]
# The H-pipe will eliminate the crackle-pop sounds you sometimes get with dual exhaust. [My system doesn't crackle-pop.]
You do not need a cross over in our car. It's not needed and there is very very little difference between the sound, unless you have an O/R H. I would keep the stock 2.25 piping. Dumps right after the muffler are most likely illegal so watch out. Oh, and don't idle in one place for too long. Emissions include carbon monoxide.
There are no Emissions testing in southern Illinois. Been driving for nearly 13 years and have yet to even hear of it coming down here anytime soon. Good thing if you seen all the redneck trucks around here lol....some have straight pipes from the exhaust manifold straight up through the hood.
Am thinking of getting tails just to address the issue with fumes coming into the cabin.
