My friend has one on his GSR. The bottom end is shit but he has a whole lot of top end to make up for the lacking bottom end power. I don't remember what #'s he pulled on the dyno though. I think in the 170's to the wheels range with ITR cams, gears, AEM CAI, Comptech header and Apexi exhaust. He is planning on an ITR TB and a JDM header/carsound cat. The larger tubing of the JDM header should help him a lot as well as with the TB.
He said it was a PITA installing it though.
