Heres a weird question, My buddy just picked up a really sweet 1973 CD 175 but it has no exhaust. I have got a set of pipes off of a 1976 750F and I was wondering if the pipe size and the flange size on the end of the pipe where it bolts to the head would fit? It would be a complete custom exhaust and we would have to bend the pipes, but just wondering if we could use this as a start?
