can you cut cats off and what will this gain or hurt
#2
you'll definately see gains.. especially on the top end... but you will throw a code in your PCM... SES light on and all.. to fix that you'd either need to get the codes deleted.. not sure how that'd work with a 96.. or you could get a O2 simulator... but that could break down the line and need to be replaced.. if you can get those codes in your PCM deleted then no worries anymore

i gutted mine... didnt see any performance add, 13.5 before/after (not 100% same conditions though, was hotter after i gutted them) but id sounded deeper... which is mainly what i did it for anyway

Taking off the cats isn't going to affect your engine in a way that it is going to want to shut off. There may be another problem you need to look into. However, if you take the cats off, you will set of the SES light. You can fix this by having the codes edited out of the PCM or buying a pair of 02 simulators and plugging them into the rear 02 sensor harnesses.

The 02 sims. will provide a "dummy" signal to the PCM that will prevent the SES light from coming on. You may still have to have the present code cleared though. As for the car running normal, the rear 02 sensors are going to have no effect on the cars drivability, you may have another issue at hand if you are having performance problems.

I took the cats out when I had my lt's installed and the car ran good for a few weeks, afterwards it started running rich and dumping lots of gas causing some of the plugs to foul up. I've heard of some people having probs with the sims, so I'm just gonna go with some hi-flo cats.
