Just got the hotshot header...this thing is SEXY!!! LOL.

I'm confused about WHY they say to extend the second o2 sensor. It says to move it behind the second cat to get "proper readings".

Heres the confusion

s14's only have ONE true cat, which is totally replaced with a header. Should i just put the second o2 sensor before the collector gasket(where it is already threaded for one) or should i move it further back on the exhaust...if so, WHY!?!?!

thanks
