This light has been on for about 2 days, it came on about a day after installing the Kinetix high flow cats on my stage 2 stillen blown 2004.5 g35 coupe.

Oil, temp etc are fine, in fact everything is dandy, more top end etc ...

Question is will this light go off by itself or am I gonna have to get the dealer to reset it and fork out $150 ??

The high flow cats can set it off.....and depending on how rich your Stillen kit runs, that can set it off as well. It is hit or miss....some high flow cats trigger the light...others dont. It may reset itself, but it may not.

Wish I had some better answers for your. Best bet is to get yourself kind of OBDII scanning tool or software, and just reset it yourself. Another option is to reset it, and then contat Skidazzle for his o2 simultor device, that prevents all O2 sensor related check engine lights.
