Finally have to do a smog check for emissions in CA

After over 6 years and 175K miles DMV is hitting me with a Smog Check.
I know for sure I have to remove the Airhammer and reinstall the stock intake, reset the adaptives and drive it a bit first.

I do have Gibson headers and teh CARB sticker to show they are compliant.

The high flow cats are a tad bit of a concern, have the Magnaflow set up that has been on for WELL over 100K miles, car seems to run real clean once warmed up so mebe I'll be OK.

I do know the guy that perform the smog check but he will not cheat it, there is a $25LK fine for that here in CA.

Any additional things I should besides bringing her in really warmed up and getting on his equipment ASAP?

the high flows shouldn't be a concern if they are in stock location, if they are moved (long tubes) then it will not pass the visual inspection.

But passing the smog part shouldn't be an issue.

You will most likely pass functional if the cats are in good condition. But you would fail visual if they look under the car, which some don't.

He does not look under the car, shorty headers, looks stock, seems to run pretty clean after warm up, running a SuperChips 91 performance tune, wondering if fueling up with 89 would have better results, may be a silly idea, it runs fine on 89 as well.

I had my CA emission testing done in March. (SF bay area) It was the enhanced test, probably the same that you'll be facing. I have heads, cam, headers, high flow cats with an ARIA intake (same as air hammer) I didn't have any issues with the visual. They couldn't get under my car to inspect the cats (2" drop) so they took my word for it. With the high flow cats, I haven't had any CELs so I passed the OBDII tests NP. The sniffer test was a bit different. I failed the hydrocarbons tests by a few PPM. I put my OEM cats back on and was near 0 for all emissions. You may have better results with the high flows than I did. Let the car run as hot as you can prior to the testing, it will help burn off the hydrocarbons.
