Cat Delete

whats up i own a 97 **** brown blazer. ive got a k&n cone filter, powerdyne throtle body spacer, dynomax cat-back, throtle body flap delete, and im thinking about cutting out my cat and just putting a piece of pipe in its place. i already went through emmisions and by the time i have to go again, the blazer should already be blown up. has anybody done this at all and if they have, am i wasting my time or is this worth doing?

Thank You

my brother did it on his 97 s dime and he got ****ty gas milage(12 mpg or worse), but a little more power (5-10 hp).
