Will a GT take-off from cats all the way back be okay for NOT throwing service engine lights? I guess what I'm asking is, are the converters the same when it comes to the computer? I don't want any more lights or bad gas mileage lol and I need my back pressure to return before I f*ck a valve in the anus. Thanks in advance.
i would ASSUME that catalytic convertors on a larger 4.6L engine would be more effecient than the cats found on a smaller 3.8/3.9L engine. if you have a handheld tuner you can just turn your MIL off anyways. but if you want to be sure you would have to ask a Ford technician what the wavelengths are recorded at the rear 02 sensor on a V6 and a V8 engine, and if the wavelengths are different, you might throw a "catalyst ineffiency" code

I think it was a "joke" only he gets...? Nevertheless I'm going to put high flows for the V6 on it and order a tuner anyway for other fun stuff. Although those MIL eliminators are cheap and effective. Does anyone not know where those are for the v6? I might just put it over a cliff and let Allstate d*ck with it =\ .....nah better not.

haha. i guess. if the high-flows throw a check engine light, then you can use your tuner to turn it off.
You can use the cats off of a GT as long as you use O2 sensors. Some people use a GT catback system along with a pacesetter adapter to bolt to the stock headers. you do not need mil eliminators, and you will not throw any codes. Especially a "catalyst inefficiency" code.
That is what I meant by the previous statement. He spends too much time on Hyundia's and doesn't know much about our Mustangs. He had you buying mil eliminators and a tuner because that was what he thought was right, not what was the truth. Most of the Ford techs do not know what we've gathered for information about our cars over the years. The rear O2 sensors are in the cats, the front O2's are in the headers......
I'm not trying to bust on you 232, just please give them the right information without having them spend money on needless things......
i never said he needed MIL eliminators?? i only said if he HAD a tuner he could use it to turn the check-engine light off. i never told him to buy anything, either. any OBD2 vehicle can get a "catalyst ineffiency code", which by the way, i said he MIGHT get one. and i know plenty about mustangs, just because hyundai signs my checks doesnt mean thats all i care about.
All disagreements aside, I know you're right about us knowing more than an textbook Ford tech because we deal with many more problems as owners and drive/experience the car on a daily basis and they see one every 2weeks maybe? Thanks for the help everyone, I think I've decided to just do a GT takeoff because I won it and no use reselling something I need and/or want, right?
Need help before Ebay auction ends please.
