I have a 2005 Road King and was wondering what exhaust I have on it, previous owner is not known.

 

Look like Rush

 

It looks like a Rush 15300 series muffler .... I base that on the fact that I have them/these on my Ultra ... and they sure look like yours ... blunt cut ends ( the metal is not rolled over on the outlet? ) and the baffle is retained by a bolt located at 6:00 near the rear of the outlet. Do a "search" here and I think you'll find some pictures of the baffle located in the muffler ... that might help you further. Also I believe that Rush and "Wild Pig" mufflers utilize the same ( interchangeable ) baffles .. Hope this helps.

 

I think it could be cycle shack or the older screaming eagle performance slip-ons.
We have a smooth transition at the inlet and use a circular mounting boss.

 

Thanks, from all of the input, I think they maybe Wild Pigs. The Cycle Shack mounting boss is not angled like mine and that seems to match the Wild Pigs pictures.
