I've accumulated four spare sets of slip-ons over the last couple of years that I have no intentions of using, so I'm in the process of trying to sell them, but.....I have one set that I have no idea who makes them, and I'm curious. I don't see anything stamped on them other than "PASO" on the mounting brackets. I can't find a name nor a model number anywhere. Here are some pictures....

I guess these are probably US made. Are the ends conical ? Wasn`t there a company called BUB having conical ends ?

I'll go with the BUBs. I have owned a few sets for Guzzis and they look like that.

"Guzzi" was a good hint.
Here a pic of BUBs on a Guzzi

Looks the same on the outlet side.....too bad my pipes aren't in better shape. If I had the time and it was worth it to me, I'd clean them up really well and paint them black....then sell them.

if you know someone with a polishing machine you could at least polish over the scratched areas. They look too deep to be totally polished away, but I think the result would still be an improvement.
