You won't pass a visual inspection if it's gone. In most multiple cat installations, everything behind the first cat really doesn't do anything.
If you don't live in an emissions state, by all means.

Why is it rubbing? one those, the first one burns one type of gas, the second burns another. It will sound better with the second missing, and since you still have the first one, you will pass a cops inspection, but if you have to get sniffed it will show, and the operator will probably know there should be a second cat.
