The two questions are not related.  The first relates to a normal mounting in 
the collector or near it, the second to a probe arrangement.  To repharse the 
question, how does one construct a probe so as to (1) not create a huge 
restriction, and (2) not "submerge" the sensor.  Do you use something like a 
closed end cylinder (a pipe say a little over 1" dia) with the sensor 
protruding from the end ?  This would position the body in somewhat "dead" 
air inside the probe but not directly in the exhaust stream.
