That's good to know.  I have 2 dyna mufflers sitting at my office waiting for me to put on.  I'll probably sell the one I don't use, provided I don't mess up the install  

I had the sportster muffler on my bike until the baffle broke out, wasnt happy with the glasspack noise so i went and found a 90 * turn out muffler that is steel baffled with basically a slight jog and straight through no glass packing , it now has a great deep roar to it , i love the sound best part it was only 40$ , instead of using the muffler and trying to get a piece of pipe fit my suggestion if its worth .02 i am not sure , cut the end off the muffler off and slightly grind it at a angle then place it on the head pipe and align it with the muffler and tack it back together, its much easier then trying to have a piece bent and having a extra connection that may leak in the future , i could post pics tommorow if you want !
