Tuning for going o/r mid pipe

[matt texass]

I just as soon get rid of the cats on my JBA mid pipe just so I don't have to worry about them collapsing or other stuff. I'm thinking about cutting the cats out and having race bullet resonators welded in their place. I already have a tune for my lt's and catted mid pipe. My question is, when tuning a catted car vs. a non catted is the only difference turning the rear 02's off? Basically am I going to have to get another tune?

you can do it either way as long as you have the bungs welded and the o2's connected. rear o2's on or off it wont matter cats or no cats.

won't you need cats to pass inspection?
