Supertrapp enthusiasts, here I got some older type 3-bolt internal disc mufflers with the tapered end caps. They look good after some years but I can't figure out for which bike they were made originally. I'm thinking about refreshing the inner mufflers with some new discs and glassfiber.

Both they have the #027-7175 on it.

Would be nice to know more about these for eg. the year they were build in and fitment details.

Thanks in advance.
