Newer engine should be fine, I don't know about the 2016 map though

Interesting thought. I forget what color they made them but if they're black or silver maybe it will sneak by. Its not like you're modifying the intake since the Power Blocks are on the engine side of the throttle body... maybe I'm just being wishful there.

TLDR: After replacing hardware and reflashing back to stock your car wont be immediately ready to smog. You'll need to drive around normally for a week or so to ensure all your sensors are re-activated.


I switched back to stock hardware and reflashed to the OEM tune. Drove out for 20 or so miles and then took the car to the smog shop. The pre-check showed the Oxygen Sensor, Catalytic Converter sensor, and Evap system were not yet active.


At the shop's recommendation, I took a drive out for 100 or so miles up in the hills. Upon my return, the O2 and Cat sensors had activated and were showing green, but the Evap sensor was not yet active. The shop said to let the car cool completely and before starting the next day, open up the fuel cap for 10 seconds and then close, before starting the car. Apparently this helps reset the Evap sensor. Otherwise, all I have to do is drive the car for about a week before the final sensor is good to go.

The EVAP usually you need to run like half a tank of gas thru the car to get them to clear. The fuel levels and air temp need to be right to get EVAP to clear.

Passed my smog but I am completely stock so this isn't a surprise.

What I found was that passing visual is 100% up to the tech's effort. He didn't look under my car, and he only gave my engine bay a glance. When I smogged an S2k a few years ago, I recalled that the smog tech was referencing exhaust images seemingly provided from the DMV on the computer, as the car was plugged in. One thing I noticed is the tech references two OEM stickers. One on the drivers door sill which he scans the barcode for quick vehicle details, and one that he needs to reference on the underside of the hood. Those of you with aftermarket hoods may not have that sticker and if he can't reference it, I'm not sure where the tech will get that information.

Yeah that's the opposite of the guy that did mine...he was using articulated mirrors looking in the engine bay and noted my extra resonator when he was under the car.

I talked to the guy for a bit afterwards and he mentioned that specifically, to save that sticker somehow if I ever got a CF hood or whatever.


I told him everything I pulled off the car for the test and asked what I could have left on and still passed and he said "none of it", lol. Now I'm pretty sure some of it was okay according to CARB appendix G or whatever it is but in the end it's probably less of a headache to just pull everything off than try to argue about it. ¯\_(ツ)_/¯

I removed the catch can and went back today and had no issues. I also have a TRD intake which removes the sound tube altogether. I have the tube capped off where it goes through the fire wall.

So here is the appendix that says closed loop air/oil separators are CARB exempt, but those exemptions may have been superseded by new regulations. I do see that there are some EO#s for air/oil separators listed on CARB's search engine. I'm curious if you printed that list and showed the guy if he would have waved you on.

When you went back did you remove it entirely or just unhook the lines? Contemplating leaving mine in the engine bay and just tying the lines to the side

I tried to explain that it is still a closed loop, doesn't vent to atmosphere, all eom parts still in place. He didn't want to get into an argument and neither did I. Next time I'll bring this info with me or maybe someone else can try and see what their tech says.

I thought about doing that originally but it was only a couple more bolts to pull the whole thing out. I would think it would be fine since it's not hook up to anything.

So a catback like the one from Perrin should be okay right? (with no other modifications)


Are all of the twins being heavily inspected? Mine has a pretty stock look aside form wheels and the perrin 2.5 catback, a quick plug and check is what I want.



I'm going to have to get mine smogged in June

Catback is fine. How close they inspect it will vary by shop and technician.

But weren’t you flapping your gums about how you knew someone that helps with hot smogs q(●‿●)p but your going this route ? U Must be a broke bish to not want to pay your boy to do the hot smog or you just wanting to throw shade. Stay in your lane primo.

I don't need one, I just know people lol

Maybe don't be a **** next time and you'll have better results.

[mswbrz]

How bout you stop being a bitch, and help someone out instead of just bragging you know someone but yet you won’t use them yourself . Fuck off man .
