I bought an '87 700F2 and I'm cleaning it up. I'm new to working on bikes but I am mechanically inclined (and, so far, I've found an answer to every question I've had in the forums here). Attached are a couple of pictures of the exhaust a previous owner installed. I just want to confirm that this is 'mickey mouse' and not standard practice. Also, I would like to know how things should actually be (a nice close-up photo would be great). It appears the metal between the pipes and the clamps were cut form Coke cans. Should this be welded instead or is it a pressure fit? Or, is there some other way everything should be connected? Thanks for the help! It does have a single Yoshi on the back.
