Flowmaster super 40s....anyone heard them yet?

Just went for a drive with the new side exit system with super 40 flows.......

ITS LOUD, quiet when cruising and loud when you get on the gas, and very very very very very deep. Its exactly what i was after.

No pics yet, but the box tips are angle cut to match the body lines, it looks great, and it fits tightly around my subframe connectors. Pics later on.
 
what are the super 40's? Straight through? I thought flowmaster just had like one chamber, 2 chamber, 3 chamber, outlaw, and hushpower or something like that.

borla stingers are far from quiet, and I think any muffler with no cats behing a big block is going to be plenty loud. My borlas used to be quiet, but as ive put more power through them they have gotten louder and louder, they are loud enough to set off car alarms at WOT with just a h/c/i 302.
I can set off car alarms with just o/r h and 2 chamber flows
