Dude...sorry to say, but give it up already....NOTHING is going to work except you pulling out the muffler and installing a factory Porsche Sports Exhaust, modifying the stock muffler, or buying a Dansk pressed sports muffler. Those are the only exhausts that don't drone at all.

The design of the location of baffles and pipe length INSIDE the muffler is what cancels out the drone. Engineers spend a lot of time figuring this out, and your universal fit Magnaflow muffler cans are not designed specifically for the Boxster, so it will give off that annoying resonance. No matter what you do to the outside of the muffler, it will not help unless you wear earplugs.
