Well, I up until I got an LS installed on Moby, neither. In the last 7+ years, I had knocked it off 4 times and damaged it enough once to require it's replacement. At the time, it cost me about $75 to replace. I have since relocated it but only because of my new exhaust setup. Rubicat has the factory skid and it seems to work fine. Of course, I just play at the mall. :crazyeyes:
