Ahh yes you are correct... I didn't have resonators, so I thought they were in the "y-pipe" portion.

Is it possible to do what I drew up in the picture to trick the post cat sensors so it doesn't throw a code? Or is that impossible? Just an idea.

If I follow your diagram you just want to put a bypass in the downpipe that has a cat in it and then place the sensor post cat?

Pretty much.

For what it's worth I do not have any sensors disabled and have been running the BP kit for over a year. I have thrown a faulty cat code one time only and cleared it and it never came back. We don't have the "sniffer" test where I live, just scans the ECU.

We scan the ECU here too in IL. The problem is that if it shows that the post cat sensors are turned off, it's a automatic fail.

It's entirely possible that setup will work. The only hiccup I see is if there would be enough diverted flow to make the sensor happy. Flow is always going to follow the path of least resistance.

I really think it's just something that would have to be tried out.

It would probably be a $500+ experiment to give it a shot.

If you don't have to pass the sniffer test, just ECU, why not use O2 simulators?

KaienZ34 · 02-25-2014, 11:33 PM

No testing or even a look under the hood or car, too bad I haz no boost.

No testing or anything like that here. Although I did get a ticket for inadequate fenders as my wheel setup is very aggressive and the side walls of my tires stick out like an inch due to the stretched tire.

I'm not very familiar with them but apparenly you screw this inbetween the existing bung and O2 sensor

I wonder if it will wonder considering these will be sitting in the headers between the engine and turbo.

This is the route I'll be going if I can't get cats on. We also switched to the scanned test for emissions, so the need for cats is not really needed. The only reason I would want to have a cats on is to prevent an MTO agent giving me a hefty fine for not having cats on the car...
