Just to throw something out there. I have a 5.0 with BBK long tubes and off road shorty X and Magnaflows. I love the way the car sounds. It has a nice little rumble at idle with a crackle from the mufflers, but the sucker is darn loud when I open it up. No 2k rpm drone while driving on the highway either. It is pretty quiet in the car, but outside, it is very noticeable.
Depending on when you wanted to get this done, I should have my car up and running in the next couple weeks. I could get a sound clip. I have always wanted to, but I never got the push to do it.
