Pro's and Con's of Gutting my CAT

I've been feeling like my cat has been going out for awhile, I bought a catback and checked as much of the cat as i could while I was down there. There were pieces of my cat falling out everywhere, I decided to have my friend Rev it real good without anything attached to the cat, and honeycomb chunks blew out everywhere, I drove it real hard without any exhaust on for a couple of miles to see if I could get anymore out. I just passed my emissions, so I am good for two years.



What are the pro's and con's of just poking everything out of my cat? How much louder will it be (compared to driving with just the cat and nothing catback?)



Thanks
