Hey guys,

I just got the following long tube headers from Stage 3 motorsports:

My friend is installing them and he says he sees a spot to put 2 of the O2 sensors, however the mustangs have 4 O2 sensors. Do you guys know what you are supposed to do with the other 2 O2 sensors? Also, if it matters, I also purchased a cat-back magnaflow exhaust.

The front O2 sensors should go in the headers, and the rear ones after the converters, if you only have 2 you need a tuner tool like predator or SCT to disable the O2 sensors, aditionally there is a part that you can conect to the O2 sensors that makes them send the right signal to the ECM so you get no codes.
The third optionwould be to weld a O2 socket into your x pipe were you can connect the sensors

So my buddy says he's going to call a muffler shop and drill some holes in the pipe and weld the other 2 O2 sensors in. Since my pipe is the off road type, do you think i'll still get codes from the O2 headers if the exhaust isn't filtered due to not having cats? He wants to keep all 4 O2 sensors since he believes having all the information from the O2 sensors during my custom tune after the supercharger goes in, is vital.
