I have searched over the site and can't find the info I need so maybe someone can help me out. I am getting ready to order my non-catted h-pipe. I have an 04 gt. Does the hpipe have bungs for the o2s? Can I just get some mil eliminators and plug them in and tie them up under the car, and plug the holes if the pipe has bungs. If not do I have to buy extensions, or can I extend the wires myself. Thanks.

 

i dont know for a 4.6 car but on both of my 50 cars there has been places for the o2 sensors

 

i only use long tubes...the bung is in the collector of the header

 

For instance, the SUM-640724 off road H-pipe to fit shorty headers does havefour O2 bungs in it but you willhave to deal with the rear O2s. For off road use only, you can use the Diablosport DBL-U7146 to turn them off. And you can simply splice the wires for the O2s but why bother, use BBK-1676 extension harness.

 

I don't know if this will help, but my off road prochamber did have the o2 in them(2) as well as 2 up front in the lt collectors. Yes, I had the o2 hooked up to the mils as well as my handheld had them shut off. Doesn't make sence, does it. The fronts are what change your air/fuel, the backs only read whats coming off the cats(which are eliminated). NO idea what the point is if the mils are hooked. I would have to assume the mils are tricking the computer and there is still something being read by the sensors. what , I don't know.
