WTB: 02 sensor to suit RS Legacy. To be welded into the dump pipe, 3 pin plug.

just go to repco and get a universal 3 pin o2 sensor from bosch. Cheap as and you just have to wire it in to the existing plug.

I would not recommend welding the O2 sensor into the dump pipe.

thanks man!!
by welding i mean welding a bung on tha dump pipe and then screwing the sensor in. i thought this was normal practice??

yes, that is normal. By your first post, It implied you were going to weld the actual o2 sensor directly into the dump pipe without the use of a threaded bung.
