Standard engineering terminology, like an exhaust joint where a smaller pipe is inserted into a larger pipe or swaged section where the OD of the small pipe and ID of the large pipe are very close so can be easily sealed.

In this instance the smaller diameter OE pipe fitted inside the 3" pipe nicely with the OD and ID being very close, they were then sealed and seam welded. There's a pic in my for sale thread, 'hybrid' I think I called it.

Problem is that the OE pipe by the flange has a few quite significant dents in it for clearance so it's not that good for high power, fine for a more modest project and very cost effective too. Replacing it will yield better results but access isn't as good, not that it's great, as Charlie at Prospeed will tell you ad nauseum... you need a Steph to get the DP nuts undone easily... and to torque the crank bolt perfectly.

Picture? sounds weird..

on my phone so can't help now, as I said, it's the same idea as most non flange exhaust joints. Pic in a for sale thread from last year, October time, hybrid downpipe.

I have a reducer and a flange that I am not going to use am keeping the other bits, have a look here linky and let me know if you are interested.
