1989 yamaha venture royale 1300 new exhaust jardine mac

I found a used set of aftermarket exhausts for my yamaha venture royale (very hard to find any aftermarket stuff for). Just a clip showing the stock exhaust and then a few quick passes with the aftermarket pipes. I think they are Jardine but I am not 100% as they have no markings on them. They appear to be well made, I have heard the mac&had varying quality when they were being produced.
