Fuel Eceonomy with Exhaust upgrade?

Hey, Anyone know what realy happens to your fuel economy when you install a Borla or Stillen or any other Cat Back exhaust system? I have heard it will get a little better, and I have heard it will get alot worse. Whats the truth? If I can get more horses and better fuel efficiency its a no brainer.
