Well.... Finally (not that I wanted it and expected it... eagerly) my car developed an exhaust leak. It seems to come from the very rear of cat converter. I'm not sure where - either from two mating flanges (there's a gap) or from a rusted weld between cat and it's rear flange.
The bolts that hold two flanges are rusted - they did a great job (rusting).
When It will get cooler, I'll run engine again and try to feel the leak by hand.
1 - if it's gap between the flanges (the bolt don't hold them together), what are the "easy" options/methods to extract all 3 bolts, clean flanges' surfaces and assemble them back? Mind that car will be on jack stands...I've no pneumatic tools at all, nor real power tools like hammer drill/chisel...
2 - if there's an additional crack at cat and flange, could that be welded? with arc or mig welder?
3 - bolts and nuts. Is there a good source of them in stainless steel flavor?
Here are some preliminary pictures...:
BTW, I'm not a welder...
EDIT:
there are the bolts that hold cat..:

Looks like I'll have to remove car with pipe and see how easy it'll be to remove those bolts.... I don't see any way to remove these bolts when pipes are installed.
