96GT, will the H-pipe cause the warning light to come on?
 

I am 90% sure it does and will this effect the way the car runs at all untill i get MIL eliminators? thanks

I ran a BBK H-Pipe w/cats for almost a year and never had a problem with the CEL coming on..... What finally set it off was the addition of the MAF/TA/Underdrive pulleys....

I can not say for sure whether it will or not.. If you get one w/o cats, it most likely will. However, you are 50/50 on the ones with cats... sometimes they set it off, sometimes they don't....

as I said, it didn't set off mine... but others on here put the same pipe on theirs, and it did trigger the CEL

I put a MAC Pro-Chamber off road pipe on my car and it took about 20 miles for the check engine light to come on. I've also put off road pipes on 96-98 cars and the light came on everytime. If you get a h or x pipe w/ cats its a 50/50 chance the light will come on like someone already said. Get the MILs and you wont have any problems.

Is there anything you can do besides buying MIL's (what are those?) that would turn the light off?

Nevermind, upon further research I found the answer to my own question...

Quoted from www.mustangworld.com in their how-to section--

MAC (nor any other manufacturer) DOES NOT guarantee that you will NOT get a check engine light illumination. If the check engine light DOES come on you have a few choices: 1) Disconnect your battery overnight and reset your computer. 2) Re-program your ECC5 computer for the mod (with an ECC programmer). 3) Buy a computer chip that takes care of the problem in it's programming. or 4) Put variable resistors in-place where the sensors would normally go to "fool" the computer. None of these methods are guaranteed to work (but do in most cases). Re-programming your computer or buying a "chip" with the new "off-road" h-pipe programming is the best way to go, to ensure 100% proper engine performance (this is what we are doing).

Well yea but if the check engine light comes on is that a bad thing??? Like will it hurt the car untillu buy a chip or whatever???

nah, it's just an eye sore/pain in the ***...I'm not sure, but i think it has something to do w/ the oxygen sensors. When you replace all four on the new exhaust, it messes w/ something, especially if you remove the cats. It doesn't do anything to your car, though...except that bothersome little light...

There's a very good chance that the car will convert to fail-safe mode while the CEL if on. It will only come on if a sensor value strays out of a pre-programmed range. The Ford Computer is designed to compensate for this by having a pre-formatted fail-safe mode that will allow the car to "limp" home with phantom values from the missing/faulty sensor readings..

SO does this hurt anything like performance or something, i didnt quite get that too much, thanks though

From what I've read out of the tech manuals, yes, it will hurt performance, as long as the light is on. The computer stays in fail-safe mode and drives on bare minimums on everything. I notice a huge difference on Accel and Shifting on mine when the light comes on, also the MPG sucks.

well ****, i already bought an H-pipe and i'm gonna install it in a couple of days, so i'm shi* out of luck untill i get some mil elimintors which i dont even know where they go, great

Hey man, don't count your self out yet..... You may not even have a problem with them....Some cars complain, some don't, you'll just have to wait and see...

Ya but I bought the one without cats and there gonna come on for sure, damn it damn it damn it, help:mad: :confused:
