It's an 18" glass-pack spray painted with black primer. When I worked in my father's shop back home, I think we picked 'em up for around $35 (give or take $20) from the wholesaler. So if this guy is actually selling them, he's got a good profit margin.
I hope we can keep this idea of putting a car/truck muffler on a bike separate from THE DARKSIDE.
Car tires on a bike are ok IMHO.
Car mufflers on a bike are not IMHO.
But if anyone is interested, I do have a couple of the glass-packs laying around back in San Angelo, and am willing to sell them for $75 each (+S&H) unpainted. They are already broken in, and if put on w/o painting would give you a nice rustic look. You would only need to add the 2" inlet and figure out what to do on the outlet that is a 2" Y currently.
