As far as it running leaner afterwards, the O2 sensors will adjust the air just like it would if you put a set of slip-ons on it. Your only going to get it too lean if you screw with the air breather then your going to need to do something about it. I did it (removed the cat) a couple weeks ago and I'm glad I did. If you had to remove that honey comb mess you too would be wondering how the hell it ran at all trying to push exhaust thru all that.

Take the stuffing out or buy some aftermarket pipes, it is not brain surgery. Remove the heat dam and the exhaust flows through faster, you don't hold as much back. The engine needs a little more fuel if you take out the cat or not, designed to run lean...we have had this converstion before!
