Does switching to a aftermarket exhaust cat-back eliminates the stock burble?

Hi guys, recently I wanted to purchase Borla S-Type Cat-Back exhaust system. The problem is I don't know if it will eliminate the burble on my 2019 BMW 440i xDrive Coupe. Can someone please help me out?

My experience is that the burble will be amplified. My friend's MPE or my Akrapovic, same case.

Burble happens waaaay before it gets to the muffler, so whatever you do from the downpipe back will only get louder than stock, stock is by far the most anti-burble setup.
