They really are similar to a glasspack, only there's no fiberglass packing material between the outer/inner walls, and the outer wall is crimped down onto the inner wall along the length of the muffler. If you look straight down one without looking at the outside, you'd probably call it a glasspack. The inside's look nearly identical (louvers and whatnot).
@SullyAwesome yeah but it does sound good. especially on the newer 08 and up 4.7l they make a lot more horses then the old 4.7l and they have more air flow as well. check out my 4.7l exhaust.
Sounds good man. Sounds like my grand cherokee straight piped. At what RPM does it sit goin 55 or 60?
