1974 Honda CB750 mystery exhaust!!!

[wardog750]

I got my bike together last week after a full top-end rebuild. went to install the exhaust that came with the bike from the junkyard and realized it was not the stock 4-4. it is a 4 into 1 exhaust that sounds amazing!!! I can't find any brand names on it or even a number stamp. It fits the bike perfectly and has no issues with fitment. I could still remove the oil filter and pan to look for chunks after the first couple warm ups. If anyone has seen this exhaust or knows of it I would like to know!! -

I have a similar- almost exactly the same pipe on mine. Sounds sooooo good. Have no idea who made it
