You are right about mostly about the sound, on the mufflers, if you google mufflers or just take a peek in this section of the forums, you will see a post that I put up that has a paste out of some article that someone else had put in another forum, relating to a modified mustang that had high HP and was used as a test car for the purposes of seeing which mufflers produced what gains on the mufflers alone. They were all pretty similar in their gains, some varied a little and in the RPM ranges of the gains. One place to look at for sound clips is the manufacturer website, altough I haven't been impressed with the Gibson clip for my year range fronty (2001), it sounded a little garbled, but the do have some for the newer ones. Another alternative is to check video sharing sites like Youtube.com and some others for people who have posted their exhaust sound clips. Good luck.
