Mr 4.9l Answer Man, got a ? for you.

Don't get too crazy, or you won't be able to drive it.

What exactly do you mean by this, loss of torque? I plan on adding the headers and a high flow cat with pipes no larger that 2.5". I want a new cat back, the dual chamber flow just isn't cutting it. I tried the single chamber and it sounded like bumble bee on crack. I know that if you have too much flow through the intake and exhaust it'll kill the torque, but if you improve the heads and cam won't that accomodate for the loss? I'm just trying to get a better understanding of how things work so I don't have to keep asking the same dumb questions. Thanks for the help.
