How do you deal with exhaust droning in the car? My car has a built 331, and it used to drone pretty loud back when I had BBK short tube headers, combined with Bassani catless x-pipe and Bassani catback. Since then I have added 18 inch resonators in the downpipes, 200 cell Magnaflow cats, and Spintech 3000 mufflers, which is the quietest performance muffler they have. It helped somewhat, but the 2000 rpm drone is still an issue to the point where I get headaches at times on a long drive. Any suggestions on how to deal with it? I've spoken to a tech at Borla who said that Windsor motors are just drone monsters and there is nothing you can do to get rid of it, starting to believe that myself.
