Courier6 is right... called a driving cycle in the manual... it does sometimes take 40-50 min... but if the downpipe adjustment LMS made...as commonly is done... was to turn off the third O2 sensor as 4DR suggests might be the case, it will still fail readiness because it will be reported on the machine as a malfunction in the emissions controls... so be sure all the O2 sensors are working.
Rejection Sticker with LMS Tune?

Just as an update to this thread:
LMS Cat'd pipes were replaced with Stock units. LMS 93 tune was put back to Stock tune. Drive-cycle was completed (~100 miles or so).
Went to the inspection station and passed. No issues.
Since this would end up being an annual DP-swap, i'm going to put the LMS-Cat'd units up for sale. PM me if interested.
Thanks again for all the help.

I am sure we could work something out for those of our customers wanting to move to the new units. Being we were first to market by a long, long time we had our downpipes out before these newer cats were even in their prototype phase. Now that they're available we already made them a free upgrade, not only making our downpipes more affordable than anyone's, but also including the much costlier cat's as part of that.
Any customer's that have our older downpipes I am sure we can work something out to get you a fair deal on the new parts if someone wanted to upgrade.

4DRHTRD said: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.
This actually is not true as far as our downpipes go. I know you had a discussion with us about our downpipes and cats last week so I am troubled that you would continue posting inaccurate information about our products after talking with us on the phone about them. I am not certain what the motiviation is behind this.

While I don't know if anyone on here specifically has them the SHO pipes were changed months ago (we just took a while to post) so there is a potential as we sell a good deal of these.

In AZ, for most cars only the readiness test and maybe visual inspection will be required. The latter is not frequent. So as long as the last O2 sensor is on for the emissions testing they'd likely pass and if the cats are present a pass is almost certain.Livernois Motorsports said:

All i can say is that my LMS Cat'd pipes were ordered and installed at this time last year. The tune files sent by LMS reflected my modifications (Airaid CAI, Corsa Exhaust, etc.). When i went to get the inspection, that's when everything came together.
Granted i knew nothing regarding OBD2 readiness as part of Mass emissions testing and was not aware that the LMS tune shut off the rear O2 sensor with Cat'd pipes. It's been a learning curve.
If there have been new LMS Cat'd pipes produced that will enable me to keep the rear O2 sensors on (via a new set of LMS tune files) and thus pass Mass emissions on a regular basis, obviously i would prefer that option. I will contact LMS to confirm that this will work. If not, i may be looking to PPE for new pipes to pass Mass emissions testing without annual DP swaps.

Sounds like a plan. I have catted PPE downpipes... which also use the largest possible Magnaflow cats.... with stock tune in a 2013 SHO they do not cause the car throw a CEL.
Same pipes without cats of course did during the testing we did.... although it takes 20-30- minutes to appear.
The combo you want to pass emission is O2 sensors (and all emissions components) turned on and no CELs however you get there
