I have the UR test pipe with the O2 extension and get the code. Could I just weld the hole a little to make it smaller? It makes sense to me but I wanted to get an opinion from someone that might have knowledge in this this.

This is the Vibrant O2 Spacer. It comes with various sized cylinders to choke the opening.

You can also turn it off in the ECU.

When I turned it off with ecuflash I get a different cell one that says the second 02 sensor isnt working at all.

Thanks man. Yeah Devin at Boostin Performance turned it off a different way and it throws a different code. That looks super complacated Im gonna try another extension if that doesnt work Im gonna look into that more in depeth.

I think I fixed it manually. I used the spark plug non-fouler trick plus some stainless steel wool in the O2 extension. Light has been off of 3 days now. Fingers crossed.
