The cats are actually in the headers.... removing the resonator box, and replacing the muffler doesn't do anything to the cat.
As long as the cats are in place, a remap isn't really necessary, although it will smooth power delivery and gain you a couple of HP.
The preferred method is to get a professional to adjust the mapping, on a dynamometer with a gas analyzer. Buying a power commander with the O2 sensor is almost as good.

"There's this adage that we have 2 ears and one mouth so we should listen twice as much as we talk. Unfortunately with the Internet people have taken this old adage and turned it around. They have two eyes and 10 fingers so they think they need to post 5 times as much as they read. And since they have 10 fingers and one brain, they only have to think 10% of the time! "
