I think there's a general agreement that the Stillen system sounds great, but drones while cruising. However, I'm pretty sure the drone can be covered up by playing music. How loud, in terms of "orange volume bars" do you have to turn the FM radio up to cover up the drone while traveling at 40, 60 80 mph? (I ask about FM stations because IPOD/ CF music tends to be louder or lower depending on quality)

 

i have no idea. depends on the song i guess. the drone is not bad if you're used to driving cars like a Supra, Z, S2K, etc.
