I don't fully agree w/ the need. I've ran both on my TPIS long tubes. Perhaps I hit closed loop a little faster with the heated unit but I checked & never seemed to drop out of closed with the stock sensor either. If you tune is good, headers are ceramic coated to keep the heat in, that exhaust is hot even at the collector of a header. Feel free to test & put your hand on mine anytime. 
Of course Y-LT-MV.
IMHO... if I had to do it over, I wouldn't bother.

With my new Hedman longtubes, I mounted a stock replacement O2 sensor in the #7 primary tube (roughly 10" from header flange, like stock), after welding a bung for it to thread into. Works fine.
