Annnd yea just reread the OP, hadn't noticed he said true dual. To the OP, that would be way more work than warranted for a 3800 FWD car. Just do a 3" single to 2.5" split at the back.
To address the torque, my car went slightly faster after I did the exhaust and that'* on a N/A motor
For mufflers it all depends on what you like. I have Cherry Bomb Pro'*, a lot of people seem to like the Magnaflows on the stock system, and there really is a large number of options for every taste
