Would this set up need special tuning or an o2 sensor or something? Or would this setup pass on its own? Note that I would be using an off the shelf tune from bpc

This is to help me decide whether I'd go with catless (aa) or catted headers (afe). Already bought the 3IM.

You need to check if your Monitors are ready. Get a cheap scanner at Harbor Freight.

I am not familiar with BPC Tune but with MHD you can tune it back to stock and do a DP Fix. You will have to do a drive cycle to be OBII ready and once it is completed you should be able to pass.

Yeah I could of worded the original question better, it was really regarding passing an emissions test with Active Autowerke catless headers and stock exhaust. I'm pretty sure I'll pass with the 3IM and a piggyback tune but will the catless headers cause me issues with an emissions test?

I'm a little confused on the subject, but this is how I understand it: the stock manifold / downpipes have a cat somewhere with a sensor that gets completely removed when doing catless headers, which gets flagged (in the odb scan) during an emissions test, resulting in failing?

I've also read somewhere that some states do not need every oem o2 sensor in the exhaust system to work in order to pass an emissions test. I assume if that's the case in jersey, than one o2 sensor missing wont cause a car to fail an emissions test?

I have AA headers, AA exhaust and AA tune (changing this to BPC once I install the 3IM for a future MILV upgrade, how do you like this tune btw?)

the tunes usually code for removed cats unless you're in a state that does smell/visual inspection (I don't think NJ has this requirement)

If you're just an OBD II scan you should be good

I haven't put the 3IM on yet and haven't done the BPC tune yet either. I was waiting to see if I wanted to do headers and get a stage 2 tune right off that bat, or just install the 3IM and bpc tune and deal with the headers later.

I've read that a lot of tunes with catless headers just consistently delete the CEL codes so they don't pop up on the dash but can still show on the emissions test. Has your AA headers caused you issues with emissions tests?

my headers have never been an issue (2/2 passed inspections in NYS) and I actually had my second done about a month ago. I can't speak for all tunes but for the one I currently have (Active)

here's a thread that goes into it a bit further.. for the BPC tune I can't advise 110% but it wouldn't hurt to ask

NJS as far as I know let's you pass with 1 not ready

This is correct. I passed NJ/NY/CT with 1 monitor not ready.

[Machspeed93]

Ah passing with 1 not ready is the exact info I was looking for. I guess I'm going with AA headers!

any leniency with not ready monitor does NOT include secondary o2. they want to see that READY. also NJ is a plug only inspection state now, some inspection stations DO have a cameras still.

That sounds about right though I don’t recall differentiating between primary and secondary. And if the o2’s are not set that usually comes with o2 related CEL which would cause you to fail inspection. Usually aftermarket tunes allow the catalyst to be not ready / incomplete.

Yes NJ has cameras underneath but they only usually check for obd1 cars or older where a visual is more necessary. For what it’s worth I passed at Secaucus no problem back in the day.
