M Performance exhaust has no drone. The closest thing to drone happens at 2200 rpm and against at around 3800 rpm, a very slight resonance where the harmonics seem to hum. We're talking a 100-rpm band where this happens, and it's something I hear but nobody else does unless I point it out and they listen closely. If the windows are up and back seats up, it's nearly inaudible inside.
