Since this is turning into more of an exhaust thread than a header thread, vis-a-vis the drone issue, I just gotta say: Corsa is unreal! Confirmed on my first highway drive today. ZERO drone at any RPM with a system that's basically straight pipes. Amazing, amazing system.
My OBX, that is a copy of Corsa, also has no drone.
