There going crazy stealing cats in San Francsico, and people dont realize that for these OEM toyota cats there getting around $150. My Dad has had two stolen (93 toy 4x4 22re), the first one they sawed off and I found him a OEM complete exhaust system to put on and then the second one they just unbolted. Anybody have any good boobytrap ideas? My toyota still has the OEM cat and I know its anyday until someone gets it if I dont do anything.  

get a budbuilt full underbody skid plate....


i would also think about gettign an alarm.... cutting of the cat will involve some motion... sure no one listens to alarms, but if its your alarm, and in your driveway or in front of the house... you might pay attention to it....
