Utah emissions exbaust question

[4ringsinutah]

Alright guys, I already know some of you are gonna give me heat for this question, and I am fully expecting it, but I will ask anyways;

So someone I know, bought a 2000 s4 with o2 and cat deletes with downpipes, and has an apr stage 2 tune that cancels those out so there are is no cel on the car. Now the exhaust is cut with no muffler so it way too loud, but this person I know is getting a new muffler put back on so it will be much quieter.

My question is this, since there is no cel, and if it is quiet when this person takes it for emmissions in slc, will this person's car pass? I have read mixed things stating that post obdII cars do not have to pass a sniffer test, only an obd read.....I also can't find any information on wether or not slc county does a visual inspection of the exhaust. If anybody knows anything about this topic, this person I know would greatly appreciate any advice that can be given. Please feel free to pm me if you want and I can pass the information on to the person I know. Thanks for any help you can give on this topic.

Don't know about Utah but if it's anything like northern va, they do obd and check readiness on your emissions as well as visual inspection. Do all inspectors visually inspect? Probably not.

I just recently went through this issue and ended up buying catalytic converters so I wouldn't have to worry about it.

Even if the tune is set up to not throw a CEL without the rear O2s, they will likely not show as "ready" in the emissions testing. If they identify this your car can be recommended to undergo further testing at their central facility. After my stage 3 build i had to re-do some stuff to have rear O2s show readiness for the annual emissions test.
You can check emissions readiness using the Android app Torque, its also nice to have for quickly checking codes etc.

Can't you set readiness with vcds?

i have actually checked readiness via the torque app and it appears that everything is good to go with the exeception of EGR and Heated catalyst;







From what i have read this should pass the OBD2 read. I believe prior owner had it tuned this way by APR so he could pass colorado emissions.

My question is, will they do a visual inspection for my Cats/O2 sensor? i have heard mixed opinions about this
