yes, you need the dummy 02 sensors that fools the computer into thinking that it has cats.

The dummy sensors are called MIL Eliminators. You'll need em if cut the cats. Personally I would use high flow cats. I lost a good bit of low end when I cut the cats off my last truck.

As long as you keep the 02s in place you my not need the mils.Some get away with out a light coming on and some don't.
