Well I can talk about this now after my cat went out on me a few months back I gutted it and put it back on. And when I did that I saw a drop in boost then the cat started to leak and the drop became larger & not to mention the loss in low end. From what I have experienced I think these motors like a good amount of back pressure and deleting the cat isn't a good idea not to mention from a environmental stand point. Since I installed my cat yesterday I haven't gotten on the gas much I don't like driving hard when the outside air temps are in the 80'* & 90'*, So I don't know how much boost has been restored. Regardless though my torque is back and the motor feels so smooth again
