I've got a Puch Proma Gran Prix exhaust that's been modded at the exhaust flange for a Minarelli V1. It would still work for a Puch... the rear mounting bracket is untouched and original.
It's got about 700 miles on it and the paint is OK. Not great. The paint near the header has come off due to heat, and there's a few nicks and flaws in the paint here and there...
Works great, I just got another exhaust, so this one is up for grabs.
I'd like 65 shipped for it.
Let me know.
I've attached a pic of the pipe when I got it and mounted it to my V1 bike...
