Question o2 sensor question

ok just a quick question would it be good to take the last o2 sensor off my exhaust? would it give it more power? ive heard that just the first o2 sensor makes the truck run richer or leaner and the last o2 sensor just regulates air after the catalytic converter?

Why would removing an emissions control sensor that helps ensure complete combustion of the fuel mixture increase power????

all the rear 02 sensors do is monitor for cat failure, they aren't robbing you of any hp or flow.
