fparrish Posted March 4, 2007 Share Posted March 4, 2007 hey, Did a search about fitting decats on my na the other day. When me and my friend went about going to fit them the first cat thats on the car appears to have a sensor going into it, is this an o2 sensor or a cat temperature sensor, is it totally necessary?! as the first decat pipe i have has no hole for it?! does one require drilling?! Please help....... Cheers, Fred. Quote Link to comment Share on other sites More sharing options...
Konrad Posted March 4, 2007 Share Posted March 4, 2007 I belive it is O2 sensor. Quote Link to comment Share on other sites More sharing options...
Steviekid Posted March 4, 2007 Share Posted March 4, 2007 It's a temperature sensor, the O2 sensors are in the exhaust manifold. It's only the UK spec that has a second 02 sensor in the second cat. Quote Link to comment Share on other sites More sharing options...
fparrish Posted March 5, 2007 Author Share Posted March 5, 2007 cheers, does that mean that if its a temperature sensor its a bit useless and can be junked? or do i have to drill holes and fit it into the first decat?! Quote Link to comment Share on other sites More sharing options...
Nic Posted March 5, 2007 Share Posted March 5, 2007 cheers, does that mean that if its a temperature sensor its a bit useless and can be junked? or do i have to drill holes and fit it into the first decat?! Just cable tie it up out of the way, no need to refit. Quote Link to comment Share on other sites More sharing options...
carl0s Posted March 5, 2007 Share Posted March 5, 2007 I cut mine off Seems fine. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted March 5, 2007 Share Posted March 5, 2007 You should NOT cut it off!! Quote Link to comment Share on other sites More sharing options...
carl0s Posted March 5, 2007 Share Posted March 5, 2007 You should NOT cut it off!! sssh. Don't say that now I was told to do so, and I have done. No going back now! oops. Is something bad going to happen? Quote Link to comment Share on other sites More sharing options...
carl0s Posted March 5, 2007 Share Posted March 5, 2007 I just didn't want it rattling about or anything. Figured it'd be tidier if it was just gone out of the way. Have I picked up some bad advice? I did it at Malcolm's house and he was saying "are you *sure* it's safe to cut off?", I was like "yeah, apparently... so the other guys have said". Plus, it was bloody rotted to the cat. It wasn't going to unscrew easily. Ooops indeed Quote Link to comment Share on other sites More sharing options...
