How to remove muffler drone!

F30 Fam,

Here is how I modified that ugly, annoying drone sound from my muffler. This idea came from my local muffler shop, thank you Crown Auto in Glendora! Genius, inexpensive quick mod! Hope you enjoy!

Measurements would be helpful to those wishing to duplicate your setup.
Specifically the length of the J Pipe.
