I have one silencer installed in my RPI, and the sound is great, NO drone at all, just smooth burbly sounds! 
It sounds SO much better than stock,still gives a boost in HP (as per Eloy), and finally lets that beautiful V8 sound out! try it, you'll love it if the sound is just a little TOO much!

I've got a Zoom Q3HD field recorder that has really good microphones, so I made a quick video on my way to the office today. IMO, you get a pretty good idea of the level of ambient noise the exhaust introduces into the cabin from this video.
BTW, none of this is pejorative towards RPI - it's a great exhaust and it sounds fantastic. I'm just not always wanting that much fantastic.
Thanks flyingpuck - I will absolutely try one silencer alone first. Did you do the drilling yourself? How did that go?

I added one silencer about a week ago. The result is perfect. About 30% or 40% less exhaust noise, nearly no drone inside the cabin, still a much more aggressive than stock sound, and no perceptible decrease in power. Just what the doctor ordered!

I'll make a video after the silencer added and post it soon. The noise level is much more livable now.
