The muffler seems a tad too long? Also, the muffler bracket hanger seems out of whack to be a Yosh.

I agree with the guys. The pipe is much too long and has not enough upsweap. I have had about every Yoshi there was in the past on my 900s and 1000s and they looked different.
74 Z1-A stock
76 KZ-900 Totaly stock vice MAC pipe
77 KZ-1000A stock
78 Z1-R 100%MINT 500 original Mi.
78 Z1-R Yoshi 1103 kit stage 1 cams Yoshi pipe. Etc
79 KZ-1300 (1400)
80 KZ-1300
81 Scratch built GPz1150R
82 KZ1000

Have a close up image from mid pipe to welded exhaust mounting bracket?

Pipe too long.... Hard to say for unknown length of swing-arm....

As for up sweep... is this a sectional Yosh?
In this case, the up sweep can be rotated to fit with slightly different angles....

Have an image of the baffle (out of pipe)...?

Here's an example of slightly different yosh (curved header) installed compared to yours....

OMR - That image of the Z1 is an excellent pic of a "real" Yosh pipes as distinguished from the sweeping bends at the exhaust ports. Yosh was a huge believer to keep the pipes from bending sharp.

But, in his ad that I posted, you can see the production pipes took a harder turn at the 1st bend, so your image may be different, yet both may be Yosh pipes??
