I'm putting together a resto mod bike that was never fully assembled. I'm attempting to put on the exhaust and it seems the spigot pipe (part of the exhaust is to long. I have removed the old crush washer. Can I cut it to match a regular spigot length? I ask bc it seems these and the spigot has a bit of a rolled edge, I assume to help even crush the washer.
1st picture is how far I can push the exhaust in. 2nd is the spigot end. 3rd is a comparison.
If the head pipes fit and look ok why not source longer studs to fit?
If they stick out to far then you have an issue. I can't see the rolled edge on the pipe very well. Is it dual wall construction? Does the stock have a rolled edge or Single or dual wall construction?
After a little more looking at your pics. Here is what I would probably do.
Carefully cut the outer wall of the new head pipes to match the length of the original. Then cut the inner pipe to a length where it could be hand formed to give you the same rolled edge as it was.
It kind of depends on your metal working capabilities. Cause it's gonna have to be close to get it to seal.
If you are lucky by cutting the outer to length the inner may just be pressed in and can be removed and cut down and slipped back into the pipe.

If just single wall cut off and leave 1/16" long. Use a cone shape bushing driver to get the rolled lip started and finish with a flat piece of steel to flatten the lip.
How does the rest of the exhaust sit with the longer header flanges? If it fits on the bike nicely as it is, just get some longer studs and bolt it up as is.
If you go cutting the pipes you might have trouble getting them perfectly straight - and then you'll have sealing issues.
