No , I don't remember what thread the pic came from but it takes a 4" bend to fab them ,any good muffler shop should be able to bend a set ,I'm going to the one I use on everything this week to have a short set like those pictured so I can run that engine ,A local father son shop and they are TOP notch , The son is so good he leaves work everyday as clean as he was when he got there in the morning and they are very busy every day ,I use them because he uses a tape measure to fit the entire system and can weld upside down better than I can on a table , The best shop I've ever used .
