I just bought a 1978 CB750f that I am going to make into a cafe racer bike. It has a 4 to 1 exhaust on it and the 4 to 1 part is in excellent condition, but the bigger end part of the exhaust (the part that bolts to the bike with the baffling stuff in it) has a giant hole in it where it looks like it was hit and then rusted through, so basically it is worthless. I need a new exhaust for the bike, and was thinking about getting a new street bike slip on style exhaust, like you would put on an R6 or similar street bike. Can that even be done? I know that I may have to get some sort of bushing to make fit nice and snug and I would have to fabricate up some sort of mounting bracket for it too, but I was wondering if/how the bike would run with that style exhaust on it. Anyone have any thoughts or help for me?
