i was fiddlin around under the hood today when i noticed a small crack in my header, i know i need a dew one but will there be any severe problems come from this if i keep driving it. all im thinkin is a small exhaust leak
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.
