LastRites, can't you just get some electrical wiring and extend the 02 sensor if you are that worried? i did this in my WRX for the same reason, the 02 sensor was just to close to the downpipe. just make sure to solder the wires, don't splice them and also use heat shrink.
you want to play you got to pay.
