Well, I just got mine in the mail today. Excited to try it out. Are you finding that it's adding power from the bottom to the top? My buddy has the SLP pipe and it seems to be spongy off the bottom- so much that it takes a longer pull to see the gains.
Mine weighs 8.4 lbs on the bathroom scale. I read on here that the stock pipe weighs 10.6 lbs with the heat shield, and 7.5 lbs without. If that's true, it would seem that the Jaws has thicker steel.
