73 340 duster exhaust tips weleded or not?

If you don't tack them at least drill and pin the hanger so they cannot slide off. Believe me if the clamp on the tip gets loose for any reason they will come off. The tip is a thick wall pipe and it is chrome plated. The exhaust is always getting hot and cool. They were prone to fall off when these cars were new. They were also easily stolen.

Yes use the clamp for originality if that's what you want. But if its a driver, So do yourself a favor and put a tack weld on or a screw in it where you don't see it or pin the hanger. I had them disappear off cars that were unattended. Just crack that clamp a little bit and see how easy it slides right off the pipe and out of the hanger.
