Ok i had bought the vibrant headers and downpipe....Well first question is should i even put these on before i get my stage 2 or should i wait till i get stage 2??

Ok and my 2nd question is do i need to hook up a gauge into my headers to tell me if im running rich or lean??

Reason im askin is because i had a few of my buddies tell me that if i put these headers on without the stage 2 i will loose alot of power and it wont be to good....also that i should hook up a gauge to my headers so i know that im not running lean and dont blow up

Thanks for the advice in advance

Putting the exhaust stuff on before or after makes no difference. It is up to you.

The way that you tell if you are rich or lean is with a wideband air/ fuel guage. It is conected to your downpipe via a bung (drilled adapter). It has nothing to do with the header itself.

You may lose a bit of lower end with the exhaust mods but get the power gain in the mid-high end. And a wideband (professionally installed) is well worth the cost, it should be one of the first mods done (IMO)
