First thing , the car will have a tune here shortly but I was planning on putting some pacesetter long tube headers on tonight and going on a club run Sunday but the car want be at the shop to tune it until sometime next week. I plan on then putting the cold air with new fuel injectors on but wanted to try the exhaust this weekend, plus putting it on takes time so having it done before the week starts will help. Just wondering if anyone has ever put long tubes on and ran an 05+ safely with no tune to adjust for the change. I know any change in the air going in requires a tune but not sure about air going out. Dont know if the on board computer will compansate and adjust for the change. Any advice would be appreciated.
Well Im guesing there nothing thats to big to be concerned about, no ones thrown a wrench at me yet for the idea. I guess it will be fine until I get to tune it next week other than the light for the lack of the 2 sensors for the cats..... There going on in 15.. keeping my fingers crossed.
I don't know about those pacesetters on a mustang, but I can tell you about my buddy who put some on his transam. He did pick up horsepower and gained .2 on his times. He's got an exahust leak though after only having them on for a week. You can hear the hissing.
Why are you putting new fuel injectors on ?

The fuel injectors I got are are the ford racing 24# .01 tolerance injectors. I got a really good deal on them and they are made to much better specs than the motorcraft 23# and guarantee equal flow on all the injectors. I figured with all the other mods I plan to put in the car they would only compliment the set up.

As far as the pacesetter headers everyone I’ve known to get the ones with the armour coat have had great success and still to this day work fine. Now they are nothing compared to kooks but when you comparing $400 to $1400 that $1000 difference is not enough to justify buying the kooks. As far as the hissing on your friends car I would say he got a bad set of headers which can happen with any number of brands like BBK, Macs and the lower end like those. I’ve even had a friend get a bad set of SLP's with the flange warped. Allot of guys are going to slam on the pacesetters and 9 times out of 10 they have no experience with them and take the first impression based off of cost. Their just as good if not better than BBK, Macs, Pypes or hooker. Ive had allot of bad experiences with BBK on a couple of my mustangs and there are no BBK mods on this mustang and there never will be so I don’t think their even comparable.
I’m assuming you mean that the readings from the O2's not being hooked up and shut off through a tune will affect the computers actions. I’m going to play it by ear literally and go easy until I get the tune on it. I have a X3 sitting around but unfortunately I can’t use it because its locked from my use on my other Mustang I sold otherwise I would use it to turn off the O2’s

You need to disable the rear O2s or you'll throw a P0420/P0430.

YES it is annoying. I would just reload the tune to fix the annoying light.

You could drive it but I would do it very carefully. No hitting the gas. And No the PCM will not be able to compensate for that much difference. You do need the front O2s and will need to turn the rears off. You can't turn off the O2s with the X3, It has to be done in the tune.

can you run Longtube headers with no tune?
