The small cats are monitored on both ends and tell the pcm how to adjust the fuel trim.
You will also get a CEL.

What about removeing the larger one?

Just trying to see if I really need all three cats to pass emissions or if I can remove one to get better Horsepower and better fuel economy, even though its a brick on wheels haha!

Assuming this is on your 01 TJ, everything is designed to be computer controlled with 2 cats. Removing them will do nothing for performance, hurt your fuel economy, and cause check engine lights and driveability issues. Spend some money on a cat-back and intake and save yourself the hassle

IMO. Not worth the time and effort.
