I think I have a Yosh series III if anyone is looking for one. Came off an 84 gpz1100 I thought I was going to use it but Im going a different route.

Finally got to taking pics of my Yosh exhaust. Primaries measure 1.5" OD and collector measures 3" before the baffle section. The fitting is for an aftermarket wideband O2 sensor by me.

My only thoughts so far is that is a rusty collector header on a Kawasaki with mag wheels. :silly:
Take a pic of the megaphone section from the collector back. Then we can determine more about who built it. :cheer:

Kawasaki


Someone once told me to marry that motorcycle I was riding ......there's times I wish I hadda listened .
