I believe that sound you hear is not from the muffler, but from the diverter valve (DV) what that does is divert or recycle excess air pressure. This sound is normal. Read all about it (and then some) here:

I am pretty sure you are hearing the report from the "noise pipe" also called the "Y" pipe. It's a wasteful little pipe that the Engineer's put in so you get a bit more "rumble" in the cabin from the exhaust.

I loved the sound too for the record!!
