New Dynomax VT Mufler

I'm not sure how loud they'd be, since it looks like only half of the muffler gets any kind of baffling, but then again, the spring-loaded valve would probably have some affect on low velocity conditions (like idle), with a little more noise cancellation than a strait-thru design.
I also wonder if there would be an increase in back-pressure in low-speed conditions (like driving around town)? I bet that would give you a little more bottom end (part throttle) on a high flowing true dual setup.
Summit's got them for about a hundred bucks.
