Other than annoying raspy exhaust sound, nasty smell and potential fines ... no not really.
Oh, and the trail of hipping bitching about it.

But seriously, I suggest a high-flow cat (Magnaflow makes nice small ones), it'll flow just as well and you can eliminate the above-mentioned issues.
A lot of guys eliminate them alltogether as part of a LongTube install. That at least eliminates the rasp.

NO, don't do it, your going to cause more smog.......





J/K
Cut them out, use small glasspacks in their place. Now it looks like you have cats, and you have eliminated some of the raspyness.
