Default Straight Pipe

I have an 87 N/A and was wondering what the benefits of a straight pipe would be in place of a catalytic converter. I realize it wouldn't pass smog but would the mpgs and hps get a little better? Maybe in conjunction with a better muffler I would see improvements? Thanks for any help.
