Topside for sure.
I have a caution about going too far back, if the sensor is needed at 
low revs (below 1500 maybe),
for instance checking idle mixture with an Innovative A/F meter.

With a big pipe you get reverse pulses of mixed fresh air in the exhaust
I moved all the way up to 2" below the flange and still the A/F reading 
below 1000 bounces all over.
