It's not annoying. I love it....for about two hours then my girlfriend starts cranking my radio or screaming to talk to me so I can hear her lol anyway, most drone is at 1.5-2.5k rpm and sometimes at 45 and highway speeds. It varies with exhaust but that's how straight piping was for me. Never again, never again.
