Does anyone know anything about these 3'' round series race mufflers? Do they prvide good sound control? How many CFM do they flow? etc.

I ran one for a while. Basically takes the mid to high pitch out of the sound. Still has a nice deep burble and growl to it. Well worth it and I think one of the best mufflers out there to use. The only one better is the round ultraflow that Gus tested on his page with the 4" inner diameter pipe, but clearance in some spots might be in issue with it.
