Just picked up an 07 E63 with a set of American Racing Headers installed, no cats, no resonators, just mufflers. The smell was really strong and the sound was super obnoxious at WOT so I decided to have a set of 200 cell cats welded in. Much better IMO. I need to get the car inspected, but I'm in NYC and there's emission testing involved. I got a guy, but he says I can't have more than one monitor in a not-ready state. Right now, I got a few more than that. Based on the Torque app, is it safe to say that I got a bunch of stuff coded out? Rear O2s? SAI? EGR? If I find them coded out, and code them back in, could the ready monitors actually go ready, or will I just end up with a CEL? Any guidance is welcome.
Each state or county will have differences in their emissions standards. Generally what is done is marking them as not ready/incomplete or not available. In states like California, both of those states will fail automatically.

NY-DMV states they follow the federal EPA so according to them, I easily fail "How Many Monitors Have to Be Ready?The US Environmental Protection Agency (EPA) guidelines allow up to two monitors to be in a "not ready" state for model year 1996 through 2000 vehicles and one monitor "not ready" for 2001 or newer model year vehicles."

It very easy i had the same problem
- you need to enable the rear o2 sensor i have xentry
- need to buy mini cats (o2 sensor cel eliminator) i have set if you need
im in nyc (queens)
Thanks Carlos. I appreciate the advice. I have Xentry too, but I haven't had a chance to get much done lately. The car had a terrible rough idle. After a smoke test revealed a poorly connected catch can as well as a cracked PCV, I pulled the manifold to address it all. Since I had the manifold out, I chose to split it to see the condition of the TBs and the plate. Sure enough it had a nice hole in it from corrosion. Glad I checked. Thankfully, Amazon sells a replacement plate for $120, so I addressed that, reassembled everything, and promptly broke the 90 degree vacuum barb off the brake booster hose where it plugs into the IM. Joy.
As soon as I find a replacement (Part # 2114303629 no longer available) I'll get in there with Star and start re-coding stuff back in.
I got it all sorted today. Car seems happy, so am I. I went into Xentry and found my way into programming, and using the W211 guide, I made my way into Control Unit Adaptations(Variant Coding) however, I guess all the instructions in the guide pertain to the ME 2.8 ECU in the E55 and not the ME 9.7 ECU from the 63. When I got to the list of options, none were numbered. So the entire instructions: "For Post Cat 02 sensors scroll down to 0182 and change Diagnose ein Diagnose aus" aren't helpful because none of the list are numbered. My German is non-existent so google translate can only help so much. I also spent several hours looking through posts with no luck.
@Carlos R which field exactly is for the downstream 02 sensors? I don't suppose you've got any screen shots? Thanks in advance
Rather than wait around for advice here, I got hold of another 63 that's stock, and went through their settings. Everything lines up exactly between both our cars. And the field which I believe is responsible for downstream 02s is called "Diagnose Dynamikpruefung HinterKatSonde" and it's currently set to "Diagnose Dynamikpruefung HKS ein."
My German buddy translated it for me: it means “behind catalyst sensor” and “ein” means “on” (“pruefung” means testing).
The other two fields I believe are relevant, and both are optioned:
Lambdaregelung --- Lambdaregelung ON, Kat.-Volumen 1 / alle BR ausser 203-/211-Allrad
Lambdaregelung (LR) Parameter --- LR Parametersatz 1 / BR 203/204/209/211/219 (ausser Allrad)
At the end of the day, I think I'll need to put the stock tune back. What's unfortunate is the My Genius hand held programmer which contains the stock tune + the V6 & V7 Eurocharged tunes, refuses to let me upload anything. It's complaining about both an error while reading hardware, and that the files are incompatible with the ECU. When I reached out to Eurocharged about this, they said that they usually see these errors when the ECU get's a software revision that doesn't match what the tunes were installed on. They also said I'd need to have the My Genius wiped, and reset (at a cost of $150 of course) and I'd have to buy a new tune in order to get a stock tune too. I've got so many opinions about that. For now, I'll reach out to the Benz Ninja. Peter is top notch and generally has a work-around for weird **** like this.

Spoiler
With the headers and 200-cell cats, it’s likely some emissions systems—like rear O2 sensors, secondary air injection (SAI), or EGR—have been coded out to prevent CELs, hence the multiple "not-ready" monitors. Re-enabling these might trigger CELs if emissions components aren’t fully functional or compatible with the car’s original ECU settings. Restoring readiness might be tough without factory-spec cats or thorough ECU tuning tailored to emissions compliance in NYC.

if your ECU software were updated by the dealer, it would have fully wiped the tune and you would be complete stock as far as the ECU is concerned. OEM process only provides a fully write to the ECU so any tunes would be overwritten completely.
So I worked with Peter (the Benz Ninja), and he was able to put the car back to stock. @hachiroku What he actually told me was, "you are running a tune on old software" so he updated it, and set it back to the stock tune all at once. So perhaps I misunderstood what Peter said, or what Eurocharge implied about the tune. Regardless, when Peter was done, I went for a short drive on the highway for about 15 minutes, and all the monitors that were unavailable or incomplete started to slowly change to complete. Funny story, the catalyst was the last holdout to go complete and the second it cleared, the check engine light came on and I cheered! For me, that was the moment I knew I was totally back to stock, and just needed to address the rear 02 sensor codes P0420 & P0430; easy peasy, I got a set of 90 degree extenders on their way and hopefully that'll do it. So far this has been incredibly aggravating to say the least. I spent hours doing research on the forums. Hours searching through the car's coding, searching through other 63 coding, and in the end I came up with very few answers. Rolling back to the stock tune just seemed like the default thing to do for troubleshooting a problem that refused to reveal itself. I still have no clue how all these emission triggers were set to off from the tune, when nothing showed off in the coding. I'm just glad it worked. Updates to come as soon as I get it completely sorted.
Update: Car is inspected. I installed the 02 extenders I ordered from Aliexpres, although they sent straight extenders instead of the 90s I thought I ordered. After clearing the codes, I went for about an hour drive and did 50 miles. No codes, no CEL, all monitors except the EVAP cleared. Thankfully, you can have 1 monitor not ready and still pass. This case is closed!
TL,DR: Bought a car with LTH and no cats. Had to install high flow cats, extend rear 02s, and put car back to stock tuning to get it to pass emissions. Thanks all! Now its on to figuring out this rough idle.
