I searched and came up with nothing, but i'm pretty sure i've read on here somewhere that there exists a jumper to eliminate the o2 sensor that's @ the cat in an ob2 civic. I have a brand new stainless magnaflow high flow 2 1/4" cat i wanna use, but it's for an obd1 (bought it when i had my 95, never got to put it on). I'm ordering a ws2 in a week and i'd like to, if possible, put the cat on as well. However i don't know if this is possible without throwing a code (i know not having it connected WILL throw a code, i'm trying to avoid that). How necessary is that o2 sensor? I would never not have a cat on my car so at worst i'll just have to shell out some beans for a new one cause i'm pretty sure my current cat has just about had it. Thanks in advance for any useful replies.

Is there a jumper, or any way to delete the o2 sensor @ the cat on an ob2 civic without a negative effect on my emissions? link=?

That o2 doesnt adjust anything, regarding fuel...but you wont pass any sort of inspection with the light on.
Just put a bung in the pipe after the cat (pre-flange) and attach the sensor. Not difficult...

the o2simulator might work

Are you taking about the pipe on the cat itself? Or the exhaust system after the cat.

sorry to thread jack but for obd2 cars does the secondary o2 sensor have to go after the cat? because the header im going to put on my car has a bung for an o2 befroe the cat and at the top of the header aswel.

Either...but in the cat would be easiest and best
