anyone ever hear of this exhaust?

my service mananger at work kid just got a FREE kz550.
no title of course and was last inspected in 1987 so it had some issues.
since we are so close to z1, i sent him out there for a bunch of parts.
carbs were real bad, i think they might be going to wg soon, it will only run on choke and all the passages are clean. whole other story for a different thread someday.

he has a chrome header on it that looks like a kerker but has the name winning on it.
i have never heard of this one before.

any one have a clue?
sounds good and seems to be in good shape so he is keeping it.

just wondering if this could be an earlier version of kerker or something?

i'm sorry i forgot my camera but will snap a couple pictures tommorrow or the next day.

The dealer I worked for sold them. The company was called Winning Performance and the pipes were basically Kerker knockoffs. The company was started by George Kerker's ex-wife, I guess she figured it was a way of sticking it to her ex-hubby.:laugh:
