Rasp and Drone
I know Rasp is the blat blat blat or rattle sound you get out of your exhaust note when there is little backpressure to level out the exhaust note pulses.However,I am not sure what Drone is.I believe it is just a humming interior resonance,but I am not sure on this subject.Anyone have any expertise they can add or rasp and drone to better understand the two?
