I'm having a couple of issues myself. I have the FM 24 and the heat sink broke at the base and came off. the baffling in my pipe is loose also so it make a nice rattling sound. I knew the exhaust note kept changing. I got one of the first ones out and thought this was an isolated issue. I for one would be glad to hear when Trinity/Epic is back up and running.

just a fyi, a Nova P5 heatsink fits. I haven't had a chance to temp the motor, but it seems to run well.
