I am installing a set of long tube headerson my 89 IROCZ i need to know where I should place the O2 sensor. I am thinking on the collector itself would be the best area. Also I need to know how to attach my O2 sensor can I just splice into the wire to make it longer or do they have an extension for it?

 

if you put it back there, youre going to need a heated o2 sensor, but i dont think youve got much of a choice
