Default Broken sensor studs

Recently bought a ‘99 rx300 with 158000 miles. The O2 sensor studs, aft of the catalytic converter have both rusted through, broke off and now the sensor is hanging. What kind of repair cost am I looking at?

You need a new section with replacement bung welded on, depending on the shop $150-400

Looking at the photo here: https://www.clublexus.com/forums/rx-...l#post11622000 if you just want to hack it you might be able to rotate it 90 degrees and clamp it on with exhaust clamps

There is going to be some sort of fabrication involved. Muffler shop may be one stop do all.

I would suggest drilling out old studs and cutting new threads and putting back the sensor. The cost will depend upon your location.
