Who the hell wants a blower that's quieter than the factory one?? Other than old men, that don't want drone in their exhaust. Isn't that half of the point? Why can't whipple or KB or lysholm make a loud blower for us? Yeah they are efficient that's great but other than the power limited eaton or a used ,probably damged 2.2, we are out of luck. Do these companies not care? It almost makes me want to go to a centrifugal. Anybody else feel them same? We should atleast have a loud or quiet option. if i have 600+ horse i want to hear it.
