My late 70’s Yoshimura (machine bent) purchased in 79 for a 750F1 hugs the bottom of the engine. It stays centered under the engine (requires center stand delete) and once collected run back where the center stand would be and s bends out and up and runs very close to the swim arm, uses factory 4/1 muffler mounting bolt at rear foot peg, muffler pipe terminating right in front of the axle nut. Close enough the nut and cotter pin would soot if you left the choke on too long (with no baffle)....terminating close enough to the nut and swing arm a box end wrench won’t clear the pipe unless the chain is junk. The pipe required exhaust studs and flanged nuts for the individual two bolt flanged pipes. Oil filter changes are easy, but engine sump oil drains on the 4/1 merge and collector.. has large 1.508 od primaries and a mechanical baffle..
I’ll get a picture of it…

I thought it looked like a late machine bent pipe someone claimed was Yoshi. I'm sure it isn't genuine but possibly was a clone. The angle makes me wonder if it is a dohc header. That said, the V&H is for dohc and it hugs the frame a lot closer.

FUBAR’s magazine ads were even better than the pipes!
