I put on Flowmaster axlebacks (the black ones). Louder than original mufflers. I don't care for the volume at 20-40 mph, but overall, pretty good choice.
I also haven't had any of the rattling or problems with broken baffles that other Flowmaster owners complain about.
Mine weren't much louder than stock when I first put them on, but they got louder as they got broken in.
I'm a novice when it comes to aftermarket. Own an '06 GT premium convert, green. Interested in a more beefed-up sound; I gather the Flowmaster American Thunder is a good, fairly economical way to go? If so, does it matter who installs them? I am considering G&K Muffler in Marietta, GA thx
