im thinking of gettin a 4-2-1 mani a raceland or something 
only thing is on all the manifolds ther is only 1 lambda take off(hole)
but on the standard 1 ther is 2?????
so wot do i need to do??

2= block the other lambda or cover it or something???
if i do this will the engine management light come on??
ive searched many previous threads but cant really find a clear answer to this???
