MAC/Yoshimura exhaust systems.

Hay guys, I know that I am getting a bit ahead of myself, but what do you think of the different Yoshi emblems that popped up over the years. There was the red badge that had the Katakana alphabet Yo-Shi-Mu-Ra characters with the English "Racing" underneath in red and white, or the all English Yoshimura oversized badge that came out on the series I and II pipes? I personally thought that the later emblems were just too busy. But that is just me. I liked the original simple red and white emblem much better. It looked like the Japanese flag with lettering. What do you guys think of a similar emblem in white on a blue background that looks like this. Mi Japanese penmanship is not the best but you will get the idea. It "Phonetically" says "Ma-Ku Ra-Se" Since the sounds in the Japanese language are very limited and do not have all the sounds we make. Maybe even underlined with a row of stars or something.

I'd be happy with any of those - mine doesn't have a badge or label and I can't find one. Blue would be best for my taste, but like I said, any would be great to have.

The original series I pipes had nothing at all than they went to a STICKER on the series I pipes. The stickers lasted about a week at best. Mine had the sticker on the Z1R.

Mark Wing has the prototype Yoshi pipe on his 650 i believe. Don't know if they ever built a production pipe for our little 4's tho. Liking my Mac Meg already.

Unless you made some mods, a 1000 pipe would not fit. The spacing of the ports is completely different on the 650/750 head than on the 900/1000/1100 head. I believe that Yoshi DID make a 650 pipe.

Oh, well that must be what I have, because it fits. I just figured the exhaust ports had the same spacing, like the intakes.

Yes, they used Mark's 650 to build the pipe and he got one free of course but it got totalled in his accident so he got another one off ebay, so yes, they went into prodction I assume.

The spacing is about 1.5" wider on the 900/1000/1100 than on the 650/750.

Good information in this post, now that leads me to this. What the heck do I have here? :blink:

That looks like a either very early hand bent Yoshi pipe or a Japanese first generation reproduction.

fast forward to 2:32 to hear a ripping yosh gs1000

The shape of those headers and the way it splits into three pieces is exactly like my Wolf pipe. The only difference is your tail piece, which looks like a yosh. My pipe had the same midpipe that was swaged on both sides. The primaries have a pressed on flange where they mate to the head, they do not use the stock half moon exhaust flanges.
I don't know a lot about Wolf I believe he was a Canadian tuner that built pipes for KZ and GS.

I don't know if Wolf made tailpipes like yours. But the wolf and yosh are both 3" OD it would be easy to graft a Yosh tail piece to the Wolf mid pipe. I know cause I have both and have thought about it.
