I have a stock DOHC exhaust that I have mocked up on my bike and it fits a little low. Mine is mocked up on a 76 750 thats got a 72 engine and uses later style exhaust clamps. I'm just waiting on some time to work on it and put the copper washers in place and it should seal up nicely. The pipes are a little blued but otherwise great and I got them for 60$ on craigslist. Try that for a SOHC exhaust.
I know no pics and it doesn't count but im 45 miles from my bike with the worst job ever so I have to disappoint
