I have a magnaflow without out cats or resonator and I have headache quality drone. I think that is where you are getting drone comments from. As stated above, people with cats and resonator are not getting any drone. You should check out the inner design of the two mufflers. Magnaflow is straight through, Rogue, Im not sure.
