Resonance is a funny thing. I don't think sound deadner helps reduce resonance that much mainly because resonance is a type vibration caused by a certain range of sound wave. While I like the sound of the 40 series I hate the noise it creates in the cab at the RPMs you normally drive. On my first truck I put the 40's where the original mufflers go and I still had the resonance in the cab at 50 - 60 mph. I vote for getting a muffler with less resonance in the range you drive your vehicle, go stock or live with it.
