Does anyone know if there is an 02 cel fix for running a cat delete test pipe. I ditched the three cats on my wrx and I bought a fix for it, but I cant find one for the b5.

You can get them at Pep Boys or whereever for a few bucks. Just thread them onto the cat & then the O2 into them. One of them will have to be drilled out a little bit to fit the tip of the O2 sensor through. It will pull the O2 far enough out of the exhaust flow to keep the CEL from coming on. I have run them for a while with no issues or CEL.

I scanned the car three minutes after startup and got two codes but no CEL. This is also about 300 miles after installation of the non foulers.

17522 - Oxygen (Lambda) Sensor: B1 S2: Internal Resistance too High
P1114 - 35-10 - - - Intermittent
16524 - Oxygen (Lambda) Sensor B1 S2: No Activity
P0140 - 35-10 - - - Intermittent

I have 2 non foulers stacked on top of each other like you have described.

Nope, no codes since they were installed. Did yours come back after you cleared them?

the no activity code posted came back after I cleared the codes right after the non-fouler install.
