Need Answers
Hay all
Im buying headers for my aus spec maxima. I need a couple of answers just to let my exhaust mechanic no exctly wat to do. Only reason im asking ive seen mixed opinions and im really wanting the right one. Witch 02 sensors are my secondary ones.? Are they the ones that are after the first 02 sensor just after the manifold.? Im going to relocate my secondary 02 sensors. I just seen a thread and pictures of someone relocating there 02 sensors after there cat. I was aware and have read through a fair few threads u have to relocate the secondary 02 sensors before the cat not after. Witch one is it?
Cheers kurt

secondary sensors are after the primary. Secondary is also called downstream which means they are down the exhaust stream from the primaries. Usually the primaries have blue wires. Just look for the sensors plugged in AFTER the precats.
