The real reason to not do it, is doing so is a Federal CRIME. Not just a fine, but you can serve jail time for it.

Is it worth that much to you?

High flow cats give little to no backpressure. Hot Rod Magazine did a test years ago and found high flow cats as good or even better than straight pipes.
