Zeitronic AFR, suggestions on where to put the Oxygen sensor


i'm thinking about installing a Zeitronic Zt-2 with a bosch wideband oxygen sensor in my 930 with GHL headers and exhaust.

Due to heat (that will destroy the sensor) Zeitronix reccomendation is to put the oxygen sensor at least 16" down the pipe from the turbo before the cat (no cat in my car).

the pipe between the turbo and the muffler is only around 5".

Any suggestions on where to put the ox sensor? is it ok to put the sensor on the pipe beween the muffler and the exhaust tip (which will give more distanse to the turbo than 16"), or should the ox sensor be places between the turbo and the muffler - in that case will the heat significantly shorten the life of the sensor?

Since there are no cat in my car my wild guessing is that after muffler installation is OK as the muffler only will change the sound, not the amount of oxygen etc. in the exhaust gas....
