hi im looking at getting an aftermarket header either a 4-2-1 or a 4-1 1 piece something like a dc sports but i have a 1990 honda crx vtec with the b16a engine as standard and the standard header has the 2 o2 sensors right up the top where it bolts onto the block. the problem im having is that all the headers i look at only have the 1 sensor location. ive got a high flow catalytic converter on the way and that has a sensor location on that aswell so can i use that for one sensor and the one on the header for the other sensor? does it matter which one goes where because i think i have 1 green one and 1 white one? also how do i go about extending the sensor wires so they reach the sensor locations? any help would be appreciated
cheers Rob
