The key difference is even loud factory exhaust setups leave room for relatively quiet operation depending on how you drive.
That Elantra driver was an idiot: he went in a town and drove in sport mode and drove in a way that forces extra loud pops
If he hadn't been forcing it the car was perfectly capable of not making excessive noise.

The $100 bozo special on the other hand has none of that: it's always loud and obnoxious.
In fact it gets more obnoxious at cruising RPM because of drone.
There are aftermarket exhausts that try to match the factory-style "not loud by default", but they're expensive because it takes careful engineering and integrating things like valves and Helmholtz resonators.
