Heres a stupid question....
chambered pipes are essentially straight thru pipes with a series of dimples pressed in. they sound great, very loud, but some beleive they do not flow very well, due to the constictions.
while on the subject, flowmaster mufflers are a chambered muffler design. they are not straight thru. the muffler has chambers formed by walls that try to cancel out the sound
superturbos have very little restriction. the flow is an 'S' shape. they use fiberglass matting to absorb sound
ultraflows are the same as superturbos, excect the flow is straight thru. ie you can see out the other side. very good flow
OEM? well i have never ripped one apart, so i don't know what their design is. anyone?

It's like the ol' side pipes, but under the car. Here's what it looks like:

As I understand it, it doesn't flow as good as 2.5" duals w/ performance mufflers, but it flows a lot better than the 2" stock exhaust.
I have them, and I love the sound. Nice rumble at idle, a great racey noticeable-but-not-too-loud sound at cruise speed (I said "racey", not "ricey"! :jester ), and a scary growl when you step on it! :D
