Well, I removed the Thrush.
The fiberglass seems to have burned out prematurely and it got really loud! I believe it is because I was running way lean and had increased heat, but it is possible that it just can't handle the higher temps of a bike exhaust. Before I removed it, I did put a slash cut chrome tip on the exit. It was looking pretty good, I think. I ordered my jet kit from Lancer and reinstalled my Dyna muffler. I guess that is what I will keep for now.
