I don't notice a drone in my car with the nameless axlebacks like I did when I had the stock mufflers on. Whenever my rpms dropped below 2k, my stock exhaust would drone like crazy to the point of setting off car alarms. With the nameless there is noise... but I wouldn't consider it droning. I'm not sure if that makes any sense but like Jason explained to me, the frequencies are different. The drone is probably due to the restrictive stock mufflers.
