06 T-RED S/C GT

Mine is a 2010 auto...with the 4.6 L + M90 blower. 94 tune. Lito had it down to a fine art, where he could tweak the tune to pass emissions, and not shut the rear o2's off in the tune. But I had VMP tune mine..and also send me a tune that did shut off the rear o2's.... then like an idiot, it ended up in my junk file..which got deleted in error. Now VMP will not shut off rear O2 sensors. I like the idea of having them on...then at least can read cat temps. If either one started to clog, its temp will also rise.
The L shaped SS non foulers don't stick out a mile like the straight ones. What ever combo works is good.
I'd sure like to know Lito's secret lol. In fact if I had the ability to datalog, I would've upgraded from my Brenspeed tunes to either Lito or Lund by now.. Unfortunately I still to this day do not own a laptop nor have an O2 sensor port/bung available to connect to one anyhow..
At any rate, I'll either look into doubling the non-foulers or just bite the bullet and go with the mini cat O2 extenders.. Just not quite sure yet at this point..
My brothers 03 GT runs stock manifold, no cats and a Mac prochamber and cat back. Passes NYS every year. He has those MIL eliminators I think they are called
I’ve tried tbe Non Foulers on my 06 without cats and I still got a CEL with the rear o2s turned on. Never tried doubling them up or a 90* turn style one either.
My main goal is to run long tubes but I’ve always been told they won’t pass NY emissions.
So it sounds like it has to be those mini cats or double non foulers or a 90* and a straight t. I’m just really hesitant on buying the long tubes to have them not work. It’s money I’m trying to save for the B326!!!
It's more than likely the Mil eliminators your brother has is the reason his car passes.. Unfortunately those eliminators will not function on 05-10 3V and 11-current Coyote models nor are they available anyhow..
From my understanding, if you double up on the non-foulers, you won't get any CEL's, as doubling them up moves the path of the exhaust gases further away from the O2 sensors by tricking them into thinking there are still cats restricting airflow.. At this point, I'm still not quite decided on either the mini cats or going the double non-fouler route.. As for buying LT's, I'm also just as hesitant as you are for the very same reasons
