I have heard superflym3's akra from 1200 to 3000 rpm range and there is no drone. Only sound you hear is the deep exhaust note and the low frequency rattle.
I became very drone sensitive after hfc xpipe with a magnaflow exhaust. It was hard to think at times. I reverted back to stock exhaust for my hearing sake
