2019 FLHT, I'm on the brink of upgrading the cam, here's where I'm asking for direction: Any recommendations for getting a Fullsac core into a Mutazu fishtail muffler? These fishtail mufflers are mounted on the bike now, and are basically straight pipes that I would like to keep. As part of the approaching cam upgrade, I have a stock head pipe, that's been de-catted, and had the crossover removed. The upgraded head pipe has not been installed yet.

Stone Cold, and Steve Cole's cam post was amazing, and informs me there has to be some type of baffle core installed in the muffler, now how I'm going to get this done?

Thanks in advance.
