When putting in a 3" body lift, do you put it on top of that block in there already?

all they do is stop up and restict flow
when they stop up they can cause manifold leaks and plenty of other things

There will be 2 codes thrown...

1. The right bank cat. con. is malfunctioning
2. The left bank cat. con. is malfunctioning

Only a tune can truly wipe them off, there is also simulators but they don't always work. As far as making the truck run bad, the short answer, it won't. The rear O2 sensors are only there to make sure the cat. con. are working, the front O2 sensors are what can change air/fuel mix, etc. I've ran my truck for over a year and a half now with no cat. con. and have had no issues with the truck over than having the trans rebuilt.
