Default WA State Emissions

All the related posts I've found are going on 10-years-old.

It's time for me to renew my tabs and I need to get an emissions test soon. I am running a Cobb stage 2 OTS map currently with a GS catless dp. Reverting back to factory ecu settings would just be a quick reflash. This is the first car I've owned that I've deleted the cats on. I've never had to think twice about getting emissions done. They check your gas cap and I think they do a sniffer test and OBD scan for codes.

I've read that people have been able to pass with catless exhaust setups. I'm wondering if it's worth it to put the stock dp back on (took off at 48k miles, car now has 61k miles.) I would rather do the swap now and pass the first time, but if it sounds likely that I can get it done catless that would save me a whole afternoon. And a whole can of PB Blaster

The OBD scan just checks for codes so if you don't have any codes I would think you would pass just fine, I'm running stage 2 as well I haven't had to do emissions yet but when I asked about it that's all they said!

No sniffer for our cars, they just read to make sure no CEL. They don't check the gas caps anymore, at least they didn't when I went a few months ago.

I had no cats with a Hydra 2.6 setup. I would just throw my tuned stock ECU back up, hook the MAF back into a temporary pipe, drive it carefully down, and pass.

No CEL = pretty much guaranteed to pass. If you fail then I would worry about swapping the DP back on.

Last check they put a thing in the tail pipe and had me rev it up, passed no problem.

Yep yep-

I was sniffed, but passed as well. They couldn't read my OBD2 port tried claiming it was on my end, but I know it was their dongle. They proceeded with the "tried and true" sniffer. Passed with nice fat rumble and service tech grumble. Stage 3 protune catless at the time.

No gas cap check, or sniffer. Only if you can't get a OBD reading. Even then you'll pass with I want to say with 3 or less of the 11 or 12 readiness/status checks.

No worries dude, this isn't Portland. We don't have mirrors on poles and Lookies-Lou's.... yet...

Yeah, the new test equipment didn't like my ecu either. They did some "waiver pass" even though I'm catted and would have passed anyways.

Yeah, they insisted my 95 Legacy is OBD1. No, it's an autotragic which means OBD2 for the 95 Legacy, trust me when I point out the OBD2 on the underhood sticker If it was a manual trans he would have been right.

I just got tested like 3 weeks ago, and I am straight piped from the header back, and passed no problem! You should be alright!

Same. Passed in November with catless stage2. No issues whatsoever. Also I hear that they are phasing out emissions testing and we prob won't need to anymore by 2016. Something about the rate of purchase for hybrids and electrics. Praise Jesus for Prius drivers.

They don't even put OBD1 vehicles on the dyno anymore. just idle and 2500 free rev sniffer.

OBD2 is just plugged in, no codes = pass.

I don't think we'll get to that point... 09+ are exempt as of 2012!
