At this point the weight savings isn't that important to me. The sound of the midpipes alone is more than enough for me. The last item is what I'm curious about. Can you give us a little insight? Will a Burger or Cobb (etc) tuned car make appreciably more power with Berk midpipes and free flowing axle back compared to just midpipes and stock axleback? It seems like there may be a point of diminishing returns.

You are taking out restriction in the exhaust system and more power is made. During the 3 weeks we spent at GIAC we saw gains with the mid pipe, but we didn't take note of it since it is merely to remove some of the restriction and for better sound.
There will be a new 3" mid pipe for the 1M very soon as well!
