testpipe cel fix

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.

Stack 2 spark plug non faulers on the rear O2 & you'll be good to go.

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.

do you get any codes with VAG-COM?

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.
