    It won't really hurt anything, but it isn't good for the exhaust flow to have an open chamber in the piping. It won't sound as good, and you can actually lose some power - believe it or not. The car will also smell like burnt fuel, since there are no catalysts to clean the exhaust gases.

    It really doesn't matter as far as inspection goes. I would save the money and just gut 'em. Or you could get high-flow cats from maganflow or some other company.

    If you live in a state where they do inspections they are known to tap on the cats and see if they are hollow then you're looking at a nice fine.......you could get some high flow cats pretty reasonable....if you dont have inspections....then yes....i'd get rid of them.......LS1's tend to burn fuel pretty efficient......

    Dude- the best thing to do is not gut the cat, just replace the cat with a straight pipe, otherwise, just get a highflow-

    The answer is "YES". For equalization of back pressure, I would change them both at the same time.
