I'm after a Cat overheat temp sensor that goes into the downpipe on my 93wrx.

I've got a deat fitted at the moment and want to fit a sportscat before my remap in Jan but can't remove the one currently fitted as it's been welded into the pipe

Anyone got one?

I have been told I don't actually need it fitted / connected, if that's the case, what can I plug the hole in the pipe with? I guess a std bolt would get a bit hot...

Thanks

Ady.

 

14mm spark plug fits i think. I smashed the top off and fitted one to the spare hole on my decat
