Years back, small exhaust shops could eliminate the need for an extensive inventory of pipes by just stocking a few different diameters and lengths and using a machine called
(IIRC) a Luth Bend-o-Graph. The machine formed a finished pipe from a set of dimensions programmed into it via IBM punchcards. If such a machine were in use today, I suppose a clever person who had the importance dimensions could program it to make just about any configuration.
