Now if you are talking about getting a testpipe or HFC, it's a different story.
Drone would be present if you removed the resonator (the one closest to your engine) and replaced it with a straight pipe. This would cause drone because of all of the exhaust gasses bouncing off of the piping and resonating to the shield and then to the cabin, but he is going to remove his rear muffler.
Every exhaust system is different and I can't speak for every car, but I can speak for the B82.0T. Example, removing the rear mufflers on my B6's aftermarket exhaust that I spent $1200 on caused drone. I have experience with the b8 platform because I've tried exactly what he was talking about before. It's crazy that this car has so many resonators and mufflers. My avant had 2 rear mufflers, 2 resonators, and a CAT :/..it was like driving a Prius without the mpg's.
Your car will not sound like it has an exhaust leak unless it has an exhaust leak.
It all depends on what your definition of proper is. Spend over $1k on a unit that changes sound, but provides no power gains
spend $50 on getting your muffler removed with similar effect
Personally I would rather spend the money on wheels/software/suspension, but that's just me
