Rejection Sticker with LMS Tune?

So i just went for an inspection sticker in my emissions-friendly state (Mass) and got notified of rejection based on "OBD Readiness Monitor Results."  I am currently running a 2013 PP SHO w/ LMS Cat'd Downpipes and their 93-octane tune.

I've contacted Anthony over at LMS who has told me i need to return to Stock programming as the downpipe tune bypasses the O2 sensors.  Obviously i would like to avoid replacing my DPipes for the sticker.

Thought I'd throw the issue out to the Forum and see if anyone else has had this issue and how they got around it.

In Arizona they check OBD2 as a "readiness" check and will fail a car for any abnormals reported to the machine. Going back
to stock reverses these and the machine reads it as OK.
Hope this helps... 15 min to fix.... 15 min to get back after.

Here's your choices:
1. Go back to stock pipes and tune and drive around until all readiness checks are passed.
2. Buy PPE downpipes and have LMS update the tune to turn the O2 back on.
I hate to tell you the 2nd option but they're the only DP I know of that don't throw readiness codes.

This is incorrect unfortunately.
You need to go back to stock or have a pipe that will pass the rear O2 readiness check. If you go back to stock with those LMS downpipes you'll throw a code like Tom did with the catless pipes. BTW, if you do put your stock pipes back on and either have an updated tune from LMS with rear O2 enabled or go with stock tune you'll need to drive around for an hour + to get to readiness pass state in your car's ECU.
Some info on this:

Can you run an anti-fouler on the rear O2 sensors so they don't throw a code on the stock tune?  Had luck with this on other cars.

4DR is correct on this......

No way around it really, unless you follow the suggestions provided.

Hopefully you saved your original factory (catted) DP's.
 
I guess that's a little bit of the confusion on my part. 

The Cat'd LMS downpipes have O2 sensor brackets and the sensors are installed on my vehicle.  I guess i'm confused on why the O2 mounts are installed on the DPipes if the tune just wipes them from the OBD system.  Do the O2 sensor still provide feedback data to the ECU (ie for A/F reasons) even if they are "deleted" from the OBD system?  A little new to the tuning world so sorry if this is an obvious question. 

How is the setup different on Cat'd LMS pipes versus the Cat'd PPE pipes?  Do they have widely different diameters?  Does the diameter of the 2 different d-pipes reflect differing exhaust volumes going past the O2 sensors?

Thanks for all the feedback.
 
And yes, i do still have my stock exhaust and DP system hanging in the rafters of the garage :)

Again, just seeing if it's a necessity to reinstall the stock d-pipes just for the sticker.

The cats on the Livernois don't pass emissions, the cats on the PPE pipes do. The Livernois pipes will pass a visual inspection but they know they'll throw a code so when you buy the pipes and a tune they just automatically send you a tune with the rear O2 programmed out from my understanding. Anybody who has bought just the pipes throw the rear O2 code and a dash light, this is why you have to program out the checking of readiness of rear O2 systems.
:)
You're going to have to reinstall the stock d-pipes and go back to stock tune.
 
That's good info to know because if I'm going to buy a Catted DP it better pass emissions or I'm going with a no cat version.

Wow that kinda blows.....LMS cannot adjust the tune to provide a false reading?

It's a readiness check the O2 has to be read and react to varying conditions. Nobody has figured it out that I know of other than a rumor of a plug in box that will do it BUT if they are ever caught selling them it's HUGE HUGE fine.
The old O2 foulers people used to use in the 90's don't work anymore from my understanding either.
You can try this:

I know my subie friend "lord forbid" said that some tuners can adjust the tune to make them look ready.Not sure how correct he was just figured i'd chime in

You can't tune to make readiness work, sorry it can't happen. Only way is to include better cats. :)

I wasn't trying to say they could. I understand how readiness works I think. I know the car will have to be returned to stock, and driven and have certain amount of key cycles to achieve readiness. LMS catted DP's don't throw codes immediately I believe when they 1st offer them people didn't start throwing up codes right away.
But it maybe just possible to return to stock and baby the car so it doesn't throw a code long enough to get it to pass.

But if not I'd give these a try before I'd start swapping DP's
