I'll order that tool for the future, in case I run across something like this.
I'm planning on driving it over to my uncle's shop tomorrow, it's a bit far about an hour's drive. (which is why I attempted to do myself first, and it's always fun learning something new)
I'm assuming it's safe to drive it like this, since there is still one bolt holding it together?
Thanks Salim!

I've found that the fire breathing wrench [torch] works every time. If you heat around the nut to expand it, you'll probably be able to turn the broken bolt out if you can get a good enough grip on it with vise grips or small pipe wrench. Heating also helps the oil penetrate deeper but be careful because it's flammable. Use a rag or paper towel to contain overspray and try to keep the spray on the threads as that's the only place that it's doing any good - the rest is just a fire hazard. Obviously, keep an extinguisher handy. I've found a torch to be a necessary tool for exhaust work esp. if you live where they salt the roads in winter. If you look at the pics of the bolts in question, you'll see quite a bit of threaded area beyond the nut that is so corroded the threads are hardly recognizable and unlikely to ever pass through the nut in order to remove the bolt. I added extra nuts to cover and protect those threads on the new bolts. Seems like a good place for stainless steel fasteners.

you can feel the exhaust leak.
To aggravate the situation, you can take a rag and momentarily choke the exit. Dont over do it as it can foul the plug.

Old thread but just want to say thank you. Here the part numbers:
Spring: 90501-35032
Bolt Flange: 90109-A0023
Gasket: 17451-0D140
PBlaster night before and than again in the AM and let sit for another hour. Wire brush everything before you start. Was very rusted but came right out. Springs could have been reused but bolts were in bad shape.
If you buy same parts from Toyota vs Lexus they 50% cheaper as long you have the part numbers.

I recently replaced my flex pipe with new bolts and gaskets. No approximately every month the forward bolts start backing out and the forward gasket fails.
The bolts are factory new for this specific application. Anyone else having this problem? Any solutions? Bent flange? Thanks.

Double nut solution would work. The nylon nut may not be able to withstand the temperature.
