I'll do that, but maybe after I make sure the motor is ok. :3
It looks like good condition OEM 4-into-4 exhausts for these things are ridiculously expensive. I might have to get a ratty OEM 4-4 and patch it up and put some cheap Harley take-offs on it or something, then paint/wrap the pipes.
Although it appears that 4/4 SOHC CB750/four exhaust will fit on it, with some of the tabs relocated, and is almost identical to the 900's stock exhaust. Those had a much longer production run, so maybe they are cheaper....
