The CEL will not come on as long as you do not delete the 2nd O2 sensors and use the spacers which lift them away from the exhaust stream...

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I'm considering a fabspeed cat bypass pipes but here in good 'ol NY we have to pass the OBD II inspection where the car will fail if there is any CEL. I wanted to see if anyone here is having luck running the O2 spacers and passing there inspection? Any comments would be appreciated (I am not concerned about the visual part of the inspection, just the diagnostic portion). Thank you.

POST 2Original post

The car will pass a NY OBII inspection... I have them on my 996 it passed everytime... The CEL will not come on as long as you do not delete the 2nd O2 sensors and use the spacers which lift them away from the exhaust stream... Go ahead and enjoy!

POST 3 / ORIGINAL POSTEROriginal post

Awesome! Thanks for the reply.. are you running the spacers from fvd or fabspeed? (Big price difference)

POST 4Original post

Clarifications! We are a motorsports supplier whom produces parts for constructors Like LOLA... Thus, you might manufacturing a cat by pass that is made from that crap you kids used in High school! Why would I spend the money, when we have the equipment and experience too manufacture our own... along with the O2 extensions (which is what the OP asked... I used)
