manifold question??

  1. #1
    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??

    1= find a mani with 2 holes?

    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???

    thanks any info will help

    Place first lambda in manifold.
    Place second lambda in sleeve.

    sleeve?? wots this how do you do this?

    its a metal sleeve that fits over the lambda to trick it into thinking its getting a clean reading after the cat, simplest way i can think of explaining it.
