I assume it's opening the stock exhaust up, making some changes inside, and then welding back together?

Hey Mike,
I have a similar mod, too, which sounds great. The muffler was opened, replaced perforated pipes by closed ones apart from a very short piece which was left perforated. Sound dampening material is still there and the Hemholtz chambers still work (reducing drone, there is none at all).
Sound is only a bit louder on the inside but way louder on the outside and it sounds great. Turning heads even at the Nürburgring where people are used to hear loud cars
.
Idle during cold start is 94db(A), idle with warm engine 74 db(A) and full acceleration (on dyno) is 116 db(A). Measured at 45 deg angle, 1m distance to exhaust tips.
