What o2 extender works?

What is going on in the picture? What are those gunks?

There used to be a mini cat honeycomb imbedded in that area that takes care of the CEL, it just dissintegrated it self .

oohhh gotcha, damn that company is selling hell of a lot of lies with the "precious metal"

Bumping up for a year later!

Curious if anyone got to the bottom of this or if we've all resorted to: 1) tune, 2) deleting the code every 5 min manually, or 3) buying a significantly overpriced piece of piping with a built in mini cat?

Lol *nervous laughter* -_-

I have tried four different spacers, with and without the "catalytic converter" materials, on 90° and straight. I either get a CEL for being too lean, heater circuit failure, or for a cat that's not working.
I can't find the happy medium. So. I'm sticking with heater circuit failure, as it seems the lesser of three evils ?

Fair. I'm currently on the FI downpipe with a CEL canceller that doesn't work. I'm also tuned in BM3 and that shit doesn't work to code out the CEL so idfk lol

I've never dealt with a car that had such a sensitive O2 sensor

So, I'm sitting here trying to figure out why we would get a fault for the heater circuit.
I have literally left O2 sensors dangling from the bottom of a car temporarily and never got that type of code. Has anyone checked their O2 sensor to see if it was damaged by installing it into the anti fowler?
I can't see how having it in or out of the exhaust stream would affect the heater circuit.

So far, so good for me. If it stops working, it's $50 bucks. Suppose I can buy another...

Would be interested to hear others that this one has worked for them. I think this was mentioned in like the first thread I found on here last Jan and it didn't work for anyone. Wonder if it works differently on 2port vs 6 as well.

So far 99% have worked, my first Cel yesterday on an m440 but I think it’s install related cause the code is for a short on the 02 sensor not the cat p0420 code

I have a basic anti-fouler, with no element in it, that I got from Autozone. The sensor hit the bottom of the fouler, so I had to add a spacer and two crush washers.
The first time I drove the car, I got a CEL for the heater circuit. Weird. I reset and didn't get it for about 200 miles. After that, I got another weird code for "malfunctioning O2 sensor" or something like that. Reset again. Knocking on wood, but I drove the rest of the way to LA, around town, then home with no CEL. I have a VSRF catted DP.
I'm trying to figure out what triggers the CEL. It seems random. I'm going to pay closer attention to how long I let the car warm up, how hard I drive it, etc.

thats weird the exact same code I got on this m440, thinking it is install related cause it is not a p0420 code

I can't remember what the second code was. It's a permanent one, so I'll check next time I'm near the car.

That's basically how it works even without a defouler. Sometimes it comes on and sometimes it doesn't. So basically it's not working the same as not having them wouldn't work to prevent a CEL. lol

Any EE degree folks want to try this out and make a kit that fits between the connections on the top of the engine?
