If you wanna hear some exhaust clips, go to mustangexhaust.com. They changed it to where you have to register to hear them, but once you do, at the very top of the forums section there are 3 sections, 1 for the 5.0L, 1 for the 4.6L, and another for the 6 bangers. I think they have some spintech and other glasspack style mufflers on there. Check it out.
