The Rotrex kit has ZERO flutter noise. I think this may have something to do with the fact that it is running a full cone filter and that creates enough restriction and muffle affect that it is not audible.

I have the muffler here for the ACE and it does quiet it down some. But it is still audible.

The ACE kit would be much quieter if you were to run the K&N filter, but it would come at a couple of psi loss.
