i live in napa and i have the same problem around my area, once i heard of this i just put a flange on both sides of my cat and made another piece of pipe with the same flanges to bolt in when i dont have to smog it. ist kind of a pain but its wortn the saved money.i hate people who have no respect for other peoples stuff. a couple months ago i got my brand new boggers slashed because someones friend "thought" i wanted to steal his sterio. luckly i watched him do it so i got my money back for them.
