I have the Magnaflow 14816 mufflers, and the Magnaflow x pipe. My local exhaust shop did all the custom piping and everything. My custom x pipe has 4 resonators and has turner test pipes, as well. I used some math and had helmholtz chambers made to eliminate the drone. The car sounds stock at 65+ MPH on the highway. I am very, very pleased with it.
