EDIT: SOLD
Bursch 1 in 1 out muffler for SC or Carrera (or '75-'77?)
Missing the mounting bracket - looks like it would be pretty simple to fabricate (see example photo
here)
Looks like it's been touched up with some high heat paint. Seems pretty solid.
Asking $100 plus shipping from Seattle (probably not cheap, this thing is fairly hefty, but I should be able to get a decent rate with my UPS account)
