I found a SuperTrapp 4'' internal disk stainless muffler today, the guy I got it from said he only put a couple of hours on it before getting rid of it, I thought to myself yeah sure, well when I got it home and opened it up sure enough, the thing is hardly used. Now I 'll need to figure out mounting. Here is pic, no dents or scratches, just a few marred spots that will polish out.
