You are going through the same issues I had with my skunkII. I added a magnaflow magnapack (it's a glass pack not a resonator, a true resonator is hard to find). I would consider this a good one and added it to the mid section (skunk comes with one in the second section already). This made the exhaust much deeper nicer sounding, lessened the volume some and reduced the drone but the drone was still there and driving me nutts. I welded the stock muffler on the rear section as a temporary fix. Sound nice but doesn't flow as good as the original skunk. I just purchased the large oval magnaflow muffler from turbo maffia (they say it's the quetest one they have). The real problem with the drone is the small canister style muffler. The resonator will help but will not solve the problem. I'll let you know the results when I get the magnaflow welded in.
