Minimal. With a turndown style exit, I don't think it's possible to eliminate drone all together but the sound that is there at freeway speeds is pretty tame.
One day when were both free I'll have to come by so that we can compare the differnce in the 2 size muffers
As far as drone, there's a section on their site that says a turn down is not suggested cause that's the only place where they have had drone with their mufflers
Charlie, what do you think of the sound at higher RPM's?
