I will link it again, this is a much better option:
Exhaust Flex Pipe Leaking
Pardon me cn90 I didn't mean to brush off your sharing of that link.
I had seen and enjoyed that idea; however it had occurred to me that by the time one removes the Manifold one might as well just replace it rather than all the work involved in splicing in a replacement flex pipe?
I am not the author of that facebook link, but from reading it, this is my understanding:
- Leave things in place.
- Use a Sawzall and cut the bad part (flex accordion portion + some of the solid pipe), leaving enough to re-connect.
- Weld the generic flex pipe to both ends and you are done.
Basically they weld both ends with the exhaust manifold in place.
Regarding the size of the flex pipe the posts I read mentioned Millimeters (65-67) which I think translated to 2-1/2 inch.
It seems the manifold side flex pipe goes IN then welded; and the tailpipe side it wraps the outside?

That is a thing you could try perhaps.
Be careful with this if your car leaks any fluids. Header wrap and other fabricky materials can soak up fluids and catch fire when the exhaust gets hot.
I got a 3" stainless flex section welded into my exhaust pipe at a local custom muffler shop for a total of ~$100, materials and labor included, and a 15-minute wait. A smaller-diameter carbon-steel flex pipe plus installation will probably be cheaper. I don't think it's worth spending $30 plus one's own time on hacked-up kinda-sorta solutions when the most-correct solution probably costs $60 and will last as long as the rest of the exhaust.

When you remove manifold,time required for welding a new flexi pipe in is about 15min.That 15 minutes includes removal of old flexi pipe and welding in a new one.
Besides flexi pipe,you will need new exhaust manifold gasket for this procedure.

It shouldn't...it's silicone.
