J pipes in the proper length and place should eliminate drone at the problematic RPM. There's a formula you use to calculate that. AFM sound is mechanical and can't be eliminated. It can be lessened, but not totally eliminated. Aftermarket exhausts make your exhaust louder. This also makes AFM louder if you still have it enabled. Series 40 FM's are loud and will drone. Typically, the louder the exhaust, the more prone to drone.
