I've installed a ScoobySport (decatted) downpipe and had a couple of cat inefficiency cels. I finally got around to relocating the O2 sensor downstream of the oe 3rd cat (must retain one for autox- also for PGT). I had my local muffler guy do this. First we checked to see if there would be enough loom to relocate the sensor- there seemed to be. Next we located a suitable spot for the sensor- we went ~ 2" behind the flange of the rear midpipe. He torched a hole in the pipe and then welded a new bung on. We used an old spark plug to plug the old bung (will be relaced w/ the proper plug when I find one). We had to zip tie the loom off of a tranny mount to keep it off the cat (would melt). He charged me $7 for the bung and only $10 for the labor (I was much undercharged:) ).

Time will tell if this works- I can't think of a reason it won't.
