Someone wanna explain NASCAR "boom tubes" to me?

I was pokin' around last night just lookin' at some parts sites, and found a place that sells NASCAR take-off exhaust systems, from the header flanges to the boom tubes. What exactly is the boom tube? I mean, I see what it IS, but what is its purpose? Does it aide in exhaust scavaging, or act somewhat like a muffler, or are the essentially straight pipes? I'm considering gettin' something like one of those setups for my Cougar, they're 3" piping and dump in front of the rear wheels just like I'm wantin', not to mention they'd look mean with the big wide exits.

The basic deal about "boom tubes" is the big wide exits are designed for a reason... When under deceleration (if you have watched a Nascar race) the cars "pop" very loud, this is from the excess fuel in the exhaust literaly exploding... A reg. 3" pipe would start to split but the wide flat exit that is used disperses this "boom" sound and violent force so the pipe and also anyone around will survive...

But also they serve another purpose... The enlarged area makes for a low pressure area also which promotes better exit flow...
