Headers and Dual Exhaust

Headers and Dual Exhaust
Tried searching this forum section only and found hits on headers and dual exhaust but never anything substantial.
I have my headers but looking to run true dual exhaust if possible but wondering about back pressure, flow streams etc and if it is feasible without making the engine run like crap.
What are the realistic options here?
This is a 2WD 3.4 swap so I have the room easily just don't want it to be more trouble than it is worth.

I'm pretty sure that O2 sensors have to close to the hotter gases of the exhaust to function properly, since they need the heat. A crossover might put them too far away.

If there is some type of eliminator 02 sensor that could trick the ecm to think its getting the right voltage...then skip the cats and do a y crossover back to whatever mufflers

No dual pipes, just a single out the back, but i could have run 2 no problem. Just have to snake them around the traction bar / rear shocks. I'm also likely going to rotate the muffler 90 degrees and tuck it up some more.
The cat i used is just behind the v-band flange (infront of the muffler) it's a "spun" cat

(they also make an OBD2 one, but i am running a rear o2 simulator... here is the OBD2 cat http://vibrantperformance.com/catalo...1022_1063_1326 )
I like these cats because they don't have anything to get hung up on, and the junkie looking to steal your cat wouldn't even know what it is...
