bending exhaust manifold?
let's say I have a mild steel 4-2-1 exhaust manifold that turns horizontally through 90 degree so the single pipe exits through the body
work.
If I wanted to lower the exist point, how could I do this?
(the fallback solution would be to enlarge the hole in the panels upwards)

cut and weld in a new section of tube? even if it will only be like an inch...
or enlarge the hole, and cover it with a nice piece of polished ali or stainless steel, with the correct size and position hole, and it covers the
enlarged one behind?

I looked into it as my westfield manifold didn't quite work on my locost, but every tube bender I tried said they wouldn;t bend a tube that had
already been bent.
In the end I got the help of a couple of very kind souls off here who sorted it for me by cut n shut!

^^^ interesting - my initial reaction would be to attempt to heat it up then try to twist it a bit - I would be looking to move the end down by 30 mm
max.

What about sand bending it?

Should be possible with lots of heat. NS Dev bent his roll cage using a big burner and a simple pipe bender, can't imagine the exhaust manifold
is made of thicker steel.
