Number one: DannyBoyDS is not me....
Number two: Exhaust sound waves cause the drone, not anything else. It is the frequency in the pipe that causes it. You have to change something in the exhaust to change the note. Think of a slide trombone, moving the slid changes the note, same thing in principle with the exhaust, change the size or the length and the note changes. You have to find the right combination for your car to eliminate the drone. You can insulate the cab and reduce the amount of drone you cane hear, but you won't change the actual exhaust frequency.
