They probably just flow a little better due to the unique resonator design -- other than that, you can't flow much more freely than an open pipe.

What do you mean, no, and then agree with me?
Also, the loss with test pipes isn't at the top end, it's at the low end, this is where the ART's correct the problem, and as said above, it bumps the torque nicely, between 15-20 ft/lbs in some cases.
