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

perhaps LMS could devise a tune that could be used to get the car to pass the test.

would hurt to ask.. would save alot of people time and possibly increase sales on their DP's

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

The code is what happens after it tries to go through the readiness check and realizes the cat isn't working to 100% efficiency.

I know when I had my speed 3 couple guys figured out which wire to soder a diode into and it would kick the false reading to trick the ecu. Could google that and do a little digging.

I say  , were there is a will there is a way .... A knowledgeable  programmer/ automotive electrical engineer COULD do this .... the average joe  cannot .. its all wrapped up in code .

I did that too on my speed 6 when I did catless downpipe, won't work on these I'm afraid.
Please try though, I could be wrong but the new O2 aren't just a resistance it's an actual feedback loop now from my understanding.

Did some reaserch, maybe this will work:

$150 for 2 (required) so it's cheaper for new purchase to just get downpipes with cats that pass readiness checks.

Man .... I sure am glad I  don't have to deal with emissions testing .

Amen to that brother...and THAT is why there is a set of NON-catted DP's in my very near future 

the O2 foulers are hit or miss.  depends on length, etc.  Worked on my Evo X MR.  But again, not 100%

I'm going to go with replacing the stock dpipes and tune and go for a re-test.

If this has to be an annual thing and if there's any interest, i might as well put the LMS dpipes up for sale and switch over to PPE Cat'd pipes.

Thanks all for the help.  Love living in an emissions friendly state!

If you go that way you won't regret the PPE pipes. I'll attest that the catted version does not throw a code in '13 SHO after almost a week. So it shouldn't in anything it fits. Just to be impartial there is at least rumor that LMS may be going to the same Magnaflow cat to avoid CELs and perhaps EPA sanctions.

Does anyone know if the non catted DP's will fail Illinois emissions standards? Soem guys with Evos were saying that the downpipes they had were non catted and were tuned out o2 sensor and passed emissions if thats the case ill go non catted
