What brand header was it?

If you leave it on there with a crack, the crack will start to expand... this will cause 2 problem... one it can potentialy be unsafe and start a fire, so you can not pass an inspection. Two you will start to loose power.

My suggestion is to make this a priority fix, not something to go into massive debt over, but it needs to be fixed relativly quickly.

A crack in the header not only lets exhaust gas out, it lets air in. This causes the O2 sensor to read incorrectly (mixture appears to be too lean), and this will affect gas mileage and performance.
