I got a call on Wednesday night from a friend the next street over who
had the catalytic converter stolen off his 4-Runner during the night.
Searching on-line, I learned that Toyota trucks/SUVs are a prime target
for catalytic converter thieves because of the high clearance and the
ease of unbolting it or cutting the pipe.
I've been looking at the various theft protection devices:
I'm thinking of just making my own with 5/16" wire rope since all of the
commercial ones use wire rope too.
Maybe I'm missing something, but I can't see why a few turns of the wire
rope on the pipe going into each side of the converter, and then
cross-pattern spiral wrapping of the converter with the cable, then
running the cable through frame members one each end would not be as
good as the "cage" of horizontal cables used by the catclamp. I went
under the vehicle and tried it with rope today to see how much cable I'd
need. and it looks like about 20' would do it. I might also use some
steel cable ties to tie the cable together where it crosses.
I'd use these bolted "swages" but I can route the cable so these are not
reachable to undo them with wrenches.
