Exhaust header dent removal?

[nzspokes]

Anbody got some cunning ideas to get the dent out?

Compressed air and carefully applied heat.

There was a fellow posted about doing just such repairs a while back. If you can't find the thread I can put you in touch.

First up don't get the wife to do this. Have a steel ball of a close diameter of the pipe welded to a chain . Heat the dent till low red heat then draw the chain through the pipe pulling the ball past the dent . Make a larger ball till you are satisfied with the result. W

Compressed air is dangerous plus not that efffective if you must use that sort of method use a water blaster.
or better still a just use a long dolly and heat.

Years back I've seen a rod welded to the dent and the dent heated red hot then skillfully pulled out. Tidy up with careful use of a grinder and buffer. I recommend the sanding flappers instead of grinding wheels.

Depends on the dent of course.
