Remove dent from header – how?

Pic shows the dent. Possibly affects function and I’m tempted just to leave it but since I got the exhaust system off, I’m wondering if this might be able to be fixed w/o screwing it up more.

The header pipes are double wall. Look inside the pipe to see if the dent affected the inner wall. You could try to pop it out from the inside out as necessary, but doubt you will have much luck as the metal is quite thick.

You use a set of expanders.....if they will reach enough. And based on the bend part, they may not work at all. Straight spots are a slam dunk though.

I have also seen gunsmiths use sand packed into bent shotgun barrels to straighten them..believe it or not it actually does work. Packed really tight, heat and repack the sand when the metals hot to build internal pressure that forces the dent outward. Takes a long time and many many cycles to get it close.
