ooo very nice (Interesting your name is 68 stepbed since that is what I have

)
I think your 4th picture will probably help the most, do you have anything that shows the pipe before that? As much before the muffler as possible
This will be great ammo already, I just want to be able to show them as much of the full length as possible since they apparently have not dealt with our years before.
Thanks so much!!!!!
