Exhaust and Gas Mileage

I was wondering how much gas mileage is affected with the addition of a catback exhaust system and an up-pipe/donwpipe combo? I am thinking about buying an exhaust/up-pipe/downpipe combo but my car is a daily driver and I don't want the addition of an exhaust to kill my gas milage.
