On an '04 ES 330. The car has a bad flex joint, which technically is one with the cat and associated piping. Has anyone bought just the flex joint? Rest of the exhaust is "like new" (Florida car). https://i.ebayimg.com/images/g/N70AAOSwiDFYP5Hp/s-l1600.jpg
Why must it be welded? I'm asking because I don't have a welder, but on the other hand, it wouldn't kill me to have it welded by someone else if needed.
Update on this. Had an shop weld a new flex joint and the car is amazingly silent. OK, obviously, but it was just barely leaking.
But the news gets better! Like a miracle, both P0420 and PO430 are gone and here all along I thought both cats were bad, but that tiny exhaust leak was messing with the secondary 02 sensors.

Glad it worked out for you! It’s a routine repair for exhaust shops to perform.
We had the exhaust noise show up around 100K on my ES330 and my mechanic said the flex joint failed. I was told all the cat converter and exhaust must be disassembled to repair the flex joint and pretty $$$. I found a welder who simply cut out and replaced the new joint up on a lift while I waited. Sooo thankful ended up costing around $100 total.
