exhaust expanders - any good?
Anyone used these to either expand/link pipes of similar dia or straighten pipes with any success?

They are really just intended for repairing damaged ends of new pipes before fitting, and for that they are a very good tool to have, if you put an
impact gun on the end they will expand a solid pipe a bit but they won't expand it enough to fit a 50mm od pipe over another 50mm od.

I have used a couple and did manage to get it to go far enough to slide over another pipe (2.25 stainless). The first one I got the thread stripped,
the second is much better. Takes quite a while though.

What happens if you heat it while expanding any thoughts?

You would need to use oxy-acetelene to apply local heat.
It would be a lot easier to use joiner sleeves used for fitting new sections to OEM exhausts or just use the next size up pipe size.

No, not any good.
If you want to tweak a bit of tube then they work, expand to create a sleeve for the same size tube then expect to fail.

I've got a yank sourced set that I've been using for twenty years and more. Much bigger centre bolt than those on ebay, and it has never
failed me. Has a proper acme thread. Tube needs to be fully annealed to help the process.
