From what I've read and stuff, headers aren't that great of an addiction to the Scion XB. It basically makes the car louder and the HP gain you get doesn't match the money you paid. I would just stick with the exhaust. The most you would gain is like 5 horsepower if that. Real HP cost serious money.
