Thanks for stopping by! So heres what I've got goin on, I have some used MILS from my 04GT that I am planning on using for when I instal my O/R H pipe next week on my 05. As far as I've heard this can be done without problem. My question is which bung do these MILS go into? I understand theres three 02 censors and the MILS only come in sets of two. Im guessing the 02 censor thats plugged into the exhaust manifold is the one that remains the same and the one where the cat used to be and behind it is where the 2 mils come into play but I just want to make sure. I think I may have this installed at a mechanic shop or something b.c I dont have a lift, any idea what kinda time this install should take these guys?? Thanks

There are 4 o2 sensors. One of them is in your left side manifold. You need the mil eliminators for the rear 2 sensors. You don't need a mechanic to do this. they simply plug in. Just borrow a set of ramps.

If you have room under there you can do the swap in about an hour, its kinda hard getting at the upper o2 sensor, other that that easy swap..

when i did mine the upper passenger o2 is a big bitch and i needed to heat up the bolts to remove the cats. Make sure you dont break the header bolts or you will need to replace. You will need to unplug the o2 censor first, dont try to take them out while pluged in or you could break the wires. Beyond that pretty straght foward.
