They look and sound good, I would like to see some dyno's, although 1 of the customer testimonials had some dyno numbers in it, and another said it worked for his dual set up.
I'm always a bit of a skeptic on those "testimonials" from manufacturers, the only ones I truly believe are on web forums like this one.
So, someone needs to buy me one of these so I can give you the scoop.
